You are probably eager to try out your new GW33 right

away and hear what it can do, rather than have to read

through a lot of instructions before you can even get a

sound out of it.

Before you do anything else, however, you should read the

PRECAUTIONS

section (page 3). This tells you briefly

how to care for your new GW33, how to avoid damaging

it, and how to ensure long-term, reliable operation.

Next, read the

GW33 SYSTEM OVERVIEW

(page 7).

This provides an important introduction to the internal

organization of the GW33, enabling you to better under-

stand its various functions and use the device to its full

potential.

To actually start using the GW33, read the

GUIDED

TOUR

(page 10). It guides you step-by-step in setting up

your GW33, connecting it properly, and (most impor-

tantly!) getting sound out of it. The section also intro-

duces you to the effect programs by letting you hear what

they are capable of, and explains how to use some of the

other main functions of the device.

The

REFERENCE

section (page 16), on the other hand,

is a comprehensive guide to all functions. You won’t need

(or want) to read through all of it at once, but it is there for

you to refer to when you need information about a certain

feature or function.

The

PANEL CONTROLS AND TERMINALS

(page 4)

is also mainly for reference. In general, look through this

section to familiarize yourself with the controls, and refer

to it when necessary.

The

INDEX

in the

APPENDIX

section (page 40) is also

very helpful. It lists page numbers for virtually every

function, feature, control and terminal found on the

GW33, and lets you find the information you need quickly

and easily.

Other parts of the

APPENDIX

section (page 36) provide

additional useful information: lists of the effect programs

of the GW33, tips on troubleshooting (when something

doesn’t work as expected), and other important informa-

tion.

Congratulations and thank you for purchasing the Yamaha GW33 Guitar Performance Effector!

The GW33 is a portable and convenient multi-effect device designed especially for guitar. The comprehen-

sive variety of high-quality effects and convenient Pedal Switch control functions make the highly portable

GW33 ideal for signal processing in home recording, studio, and live performance applications.

Some of the advanced features of the GW33 include:

• Eight independent effect blocks, including Compressor, Distortion/Insert, Equalizer/Amp Simula-

tor, Modulation 1/2, Delay, Reverb, and Noise Gate. The two Modulation blocks allow you to have

two different modulation effects simultaneously.

• A wide variety of high-quality distortion effects, utilizing both analog and digital distortion circuits.

• Twenty-five professionally created Preset effect programs, for use in a wide variety of processing

applications, plus twenty-five User memory locations for saving your own effect programs.

• A separate send/return loop (Insert) for integrating external effects into the GW33 effect chain.

• Convenient parameter control over all effects, yet exceptional ease-of-use — you can adjust the

parameters of the effect blocks much as you would on conventional pedal effects.

• Consistent, continuous Delay/Reverb decay, letting you switch between similarly set programs

without cutting off the Delay/Reverb sound.

• Foot Controller input, for connection of an optional FC7 Foot Controller, giving you convenient

volume control as well as realtime adjustment of the Pedal Wah effect.

• Built-in tuner, allowing you to tune your instrument without removing it from the signal chain.

• Built-in metronome, with fully adjustable time signature and tempo. The metronome provides both

visual indication and an audio click for maximum flexibility.

■ USE THE CORRECT POWER SUPPLY

Power to the GW33 should be supplied only from the

appropriate Yamaha AC adaptor (the PA-3, or another

adaptor recommended by Yamaha). Use of another

adaptor may cause serious damage to the unit. (Never use

the PA-3B.) Also make sure that the adaptor you have is

appropriate for the AC mains supply voltage in the area

where you intend to use the GW33. (The correct input

voltage is marked on the adaptor.)

■ AVOID EXCESSIVE HEAT, HUMIDITY, DUST

AND VIBRATION

Keep the unit away from locations where it is likely to be

exposed to high temperatures (such as direct sunlight) or

humidity. Also avoid locations which are subject to

excessive dust accumulation or vibration which could

cause mechanical damage.

■ AVOID PHYSICAL SHOCKS

Although the GW33 has been constructed to withstand the

normal rigors of stage and studio use for optimum sturdi-

ness and reliability, avoid subjecting it to strong physical

shocks (such as dropping or hitting it), since this may

damage the unit. Since the GW33 is a precision-made

electronic device, also avoid applying excessive force to

the various controls.

■ DO NOT OPEN THE CASE OR ATTEMPT

REPAIRS OR MODIFICATIONS YOURSELF

This product contains no user-serviceable parts. Refer all

maintenance to qualified Yamaha service personnel.

Opening the case and/or tampering in any way with the

internal circuitry will void the warranty.

■ MAKE SURE POWER IS OFF BEFORE MAK-

ING OR REMOVING CONNECTIONS

Always turn the power off prior to connecting or discon-

necting cables.

■ HANDLE ALL CONNECTIONS CAREFULLY

Always be careful to connect and disconnect all cables and

cords by gripping the connector itself, not by pulling on

the cord.

■ CLEAN WITH A SOFT, DRY CLOTH

Never use solvents such as benzine or thinner to clean the

unit, since these will damage the finish. Wipe clean with a

soft, dry cloth. If necessary, use a soft, clean slightly

moistened cloth — making sure to wipe the case off again

with a dry cloth.

■ ELECTRICAL INTERFERENCE

Since the GW33 contains digital circuitry, it may cause

interference and noise if placed too close to TV sets,

radios or similar equipment. If such a problem occurs,

move the GW33 further away from the affected equip-

ment.

This section shows and explains all of the controls and terminals of the GW33. Since the expla-

nations below are fairly brief, you should turn to the page references given for more information

on individual buttons and features. Refer to this section also as necessary when using the GW33,

when you need specific information on a certain control or terminal.

This section provides a brief overview of the GW33 — the basic structure of its various functions

and the memory system. Once you gain a general understanding of the internal workings of the

GW33 as given here, you’ll have the tools for taking full advantage of its features.

The diagram below shows the internal system of the

effects and other functions of the GW33.

The GW33 is equipped with a comprehensive set of

effects designed specifically for the guitar player. Up to

eight different effects can be used simultaneously. More-

over, a special Insert block lets you connect additional

external effect units to the multi-effect chain of the GW33.

Individual effects (excepting Noise Gate) can be turned on

and off as needed with the Pedal Switches and can be

quickly and easily adjusted with the Parameter Dials.

There are eight main effect blocks and a total of thirty-one

different effect types:

(Refer to the EFFECTS AND PARAMETERS section,

page 20, for more detailed descriptions and explanations

of these effects.)

With all these various effects, used individually or simul-

taneously, the GW33 has all you need to augment your

sound, whatever the application. Plus, flexible effect

bypass (on/off) functions give you even more realtime

control over the sound. A programmable Noise Gate is

also included for filtering out hum, hiss and other undesir-

able noise. (See page 29.)

The Effect Structure of the GW33

Keep in mind as you use the GW33 that the structure of its

effects is basically in a four-part hierarchy: 1) Effect

programs, 2) Effect blocks, 3) Effect types, and 4) Effect

parameters.

An effect program consists of eight different effect blocks,

all of which can be used simultaneously. A block includes

one or more effect types, one of which can be used at a

time. And each effect type has up to four different param-

eters, which allow you to set the sound of the effect. The

logic of this structure is reflected in the panel layout, with

effect blocks, types and parameters printed in a matrix

from left to right.

Memory Structure

The GW33 has a total of 50 effect programs, divided into

ten banks of five programs each. The 25 programs from

61 – 05 are Preset programs. Programs 11 – 55 are User

programs, and your own original settings can be stored to

these.

Once you’ve taken your GW33 out of the box and are ready to use it, you’ll have to make a few

connections and follow some simple instructions on setting it up.

GUIDED TOUR

When using your GW33 for the first time, read through this short section of the

manual. It guides you step-by-step in all basic operations: setting the instrument

up, connecting it properly to other equipment, and playing the effect programs.

Headphones

Signals are output through

the OUTPUT jacks, even

when headphones are

connected.

Adjust the headphone

volume with the Total Level

parameter (see page 31).

When using a single guitar amp, connect to

the L/MONO OUTPUT jack.

First, make sure that the power switch on the GW33

is off before making ANY connections.

Plug the DC output cable from the supplied PA-3

adaptor (or another adaptor recommended by

Yamaha) (Never use the PA-3B.) into the DC IN

terminal on the rear panel, then plug the adaptor into

a convenient AC outlet.

The cable clip located next to this terminal helps to

prevent accidental unplugging of the power supply

during use. Wrap the adaptor cord firmly around the

clip (see the Rear Panel illustration, page 10).

CAUTION! ■

Do not attempt to use a different

AC adaptor with the GW33. (See the precaution

on page 3.)

Plug your instrument into the INPUT jack on the rear

panel.

For the sake of these instructions, we’ll assume

you’re using an electric guitar; however, most any

electronic instrument can be used.

NOTE ■

You should be careful if you are connecting

a synthesizer or electronic keyboard. Since their

output level is generally much higher than that of a

guitar, the volume control on the instrument should

be turned down accordingly.

Connect the GW33 output or outputs to your ampli-

fier/speaker system, as shown on page 10. Before

you do this, however, make sure that the power on

the system is first turned off and all volume controls

are set to zero — this includes the guitar controls and

the volume on the connected amp(s).

NOTE ■

Use the clean channel of the amplifier for

best results.

If you are using an optional FC7 Foot Controller

with the GW33, connect it to the FOOT CONTROL-

LER input jack on the rear panel. Make sure that the

pedal is at or near the maximum position.

Turn on the power of all the equipment, starting with

the GW33, and turning on the connected amplifier

last.

Before you turn up the volume and try to play, set all

the effects to off by using the Bypass function.

To do this, simultaneously press and hold down

Pedal Switches 2 and 3. Keep holding them down

(for roughly one second) until “bP” (Bypass)

appears in the BANK/MEMORY indicator.

This temporarily turns off all effect processing, and

lets you hear the “dry” input signal.

Now, set your guitar to a suitable volume. Next,

slowly bring up the level of the connected amplifier

as you play, until the level is suitable.

Finally, turn the Bypass function off by pressing any

one of the Pedal Switches (1 – 5 or B).

If you’ve followed all these instructions carefully,

you should now be able to hear the sound of your

guitar processed by the effects of the GW33, and are

able to try out some of the other effect programs of

the GW33. If no sound is output or the sound isn’t as

you expect, refer to the Troubleshooting section on

page 36.

Notice that all the program numbers have two digits.

The first digit indicates the bank and the second

the Pedal Switches 1 – 5, you can select one of five

programs in the currently selected bank.

The GW33 makes it extremely easy to adjust or change the sound of the effects. In this section,

you’ll learn how to change the effect type and use the Parameter Dials to change effect settings.

You’ll also learn how to compare the edited program with the original. Finally, you’ll learn how

save the new effect program you’ve created.

Editing an Effect Program

Select one of the User or Preset effect programs.

Although any effect program will do, select

program number 11 for this example.

NOTE ■

The on/off switching of the MOD 1/2 and

Delay/Reverb blocks is determined by the On/Off

parameter of those blocks. (See pages 24 and 27.)

Use the y and n buttons to select the

desired effect block row (in the parameter matrix

printed on the panel). (The lamp at the left of the

corresponding block lights.) For this example, press

either button repeatedly until the Distortion/Insert

block is selected.

NOTE ■

Even though creating and saving your own

effect program erases the previously stored program,

you can restore that particular factory Preset pro-

gram. Refer to RESTORING FACTORY-SET

EFFECT PROGRAMS on page 33 for details. Keep

in mind, however, that restoring the factory Preset

program will irretrievably erase the effect you’ve

created. For this reason, you may want to keep a

written record of the settings you make (using a copy

of the Blank Effect Parameter Chart on page 38), so

that you can reprogram the effect later if necessary.

Next, press the e button to enable

the Edit mode. (The EDIT/COMPARE lamp

lights and the ON/OFF lamp above the Bank Pedal

Switch flashes.)

displays it so that you can check it against the value

you’ve edited.

Each press of the e button switches back

and forth between the original program (lamp flashes) and

your new edits (lamp lights continuously).

When you’ve adjusted the sound to your satisfaction, you

may wish to save it for future recall. You can either copy

the settings down on paper (using a copy of the Blank

Effect Parameter Chart on page 38) or go on to the next

section and save the settings to the GW33’s memory.

CAUTION! ■

Be careful not to press the

button while editing. If you do, the original effect

program’s settings will be called up, erasing all

settings you had made to that point.

Saving an Effect Program

Now that you’ve created your own original effect pro-

gram, you will want to save the settings to a program

number, so that you can recall your new effect program in

the future. (For more information on saving effect pro-

grams and other matters relating to memory, see the

SYSTEM OVERVIEW section on page 7.)

If you’ve continued from the last section and have

new settings you want to save, press the

s button.

The SWAP/WRITE lamp lights and the program

number in the BANK/MEMORY indicator flashes

to indicate that the GW33 is ready to write the

settings to memory at the selected program number.

If you want to save the program to the current

number, skip to step #3. If you want to select a

different program for saving the new program, go to

the next step.

NOTE ■

Edited programs can be saved to the User

effect programs, in banks 1 – 5. Banks 6 – 0 are

reserved for the Preset effect programs, and cannot

be used to save edited programs.

NOTE ■

When you’ve edited one of the Preset

programs (61 – 05) and try to save it, “—” appears in

the BANK/MEMORY indicator until you select one of

the User program numbers (11 – 55).

If desired, select the destination User program

number (11 – 55) by using Parameter Dial A.

Keep in mind that the programs that you edit can

In the Play or Edit modes, any of the main effect blocks can be individually turned on or off with

the Pedal Switches. (Switching of Modulation 1/2, and Delay/Reverb is dependent on the On/Off

settings of those effect blocks; see pages 24 and 27.)

OPERATION

With the Play mode enabled (press the p

button if necessary), press Pedal Switch B twice

quickly so that the lamp above the Pedal Switch

flashes. This same condition is called up automati-

cally when entering the Edit mode.

Press the appropriate Pedal Switch to turn the

desired effect block on or off. (The lamp above the

Pedal Switch lights or goes out accordingly.)

To cancel the effect on/off operation and return to

normal effect program selection, press Pedal

Switch B again. (The lamp goes out.)

NOTE ■

The effect on/off changes that you make here

are temporary. The original on/off settings are re-

stored as soon as you change programs. The on/off

switching of the MOD 1/2 and Delay/Reverb blocks is

determined by the On/Off parameter of those blocks.

(See pages 24 and 27.)

will call up the original effect program’s settings and erase all settings you had made to that

point.

OPERATION

Select an effect program for editing and press the

e button to enable the Edit mode.

(The EDIT/COMPARE lamp lights and the ON/OFF

lamp above Pedal Switch B flashes.)

Use Pedal Switches 1 – 5 to turn on the desired

effect blocks.

HINT ■

Since you’ll probably want to listen to the

changes as you make them, make sure that all

relevant effect blocks are turned on. Better yet, turn off

all blocks except the one you are editing. This lets you

clearly hear only the effect you wish to edit. (One

possible exception to this guideline is the Amp Simula-

tor effect, changes to which are easier to hear when

Distortion is also on.)

Use the y and n buttons to select the

desired effect block row (in the parameter matrix

printed on the panel). (The lamp at the left of the

corresponding block lights.)

NOTE ■

The TUNER/METRONOME row cannot be

selected in the Edit mode.

Use the Parameter Dials to adjust the effect param-

eters.

relatively high values before adjusting any other

parameters. Doing this ensures that any changes you

make with the other Parameter Dials will be fairly

noticeable.

For information about each of the effects and their

parameters, refer to the section EFFECTS AND

PARAMETERS on page 20.

HINT 2 ■

If you are using the optional FC7 Foot

Controller, try experimenting with the Foot Controller-

related Volume Position, Minimum Volume and Total

Level parameters in the Noise Gate/Utility block. (See

FOOT CONTROLLER OPERATIONS on page 30.)

Save the new settings to memory, if desired. (See

the section SAVING EFFECT PROGRAMS on

page 31 for details.)

■ Compare Mode

While editing an effect program, you can compare the

sound of the newly edited program with the original

one.

To do this, press the e button (during

editing). (The EDIT/COMPARE lamp flashes to

indicate the Compare mode is active.)

■ Parameter Check Mode

When editing an effect program, the Parameter Check

mode allows you to view the newly edited parameter

values of a selected effect block without changing

them.

To do this, select an effect block (during editing, when

the EDIT/COMPARE lamp is lit continuously).

Then, simultaneously press the y and n

buttons. (The selected effect block lamp flashes to

indicate the Parameter Check mode is active.)

To view the edited parameter values for the selected

effect block, turn the corresponding Parameter Dials.

As in the Compare mode, values cannot be changed in

this condition.

To return to normal editing, press one of the y

and n buttons.

Checking Parameter Values in the Play Mode

You can also check parameter values while in the play

mode. To do this:

Use the y and n buttons to select

Compressor Block

The Compressor is especially effective for guitar since it

smooths out the “peaks” and “valleys” in the sound.

Compression “squashes” the dynamic range of the signal,

making loud signals softer and soft signals louder. Nor-

mally, the Compressor limits signals of widely varying

loudness to a dynamic range more suitable for use with the

other effects. For this reason, compression is effective on

guitar in smoothing out the level differences caused by

uneven picking technique.

—

(No parameter for this Parameter Dial.)

Attack Range: 1 – 16

Determines the amount of time it takes for compression to

begin after an input signal is detected. Longer attack

times let through more of the natural attack of the input

signal.

Sense Range: 1 – 16

Determines the degree of compression. Maximum values

result in a smaller dynamic range, where originally loud

sounds become soft, and vice versa. This increases the

sustain of the sound.

—

(No parameter for this Parameter Dial.)

Level Range: 0 – 15

Determines the level of the Compressor sound. Higher

settings are used for boosting the overall signal to an

appropriate level, since compression effectively lowers the

level of the sound.

HINT ■

The Level parameter should be set to an appro-

priate value to avoid sudden jumps or drops in level when

switching the Compressor block on and off.

The Distortion/Insert block features three basic Overdrive

and Distortion effects arranged in twelve different types.

(The types are printed on the left side of the panel for easy

reference.)

The block also features an Insert section, letting you put

an external effect into the effect chain of the GW33.

(Connect the external effect to the SEND and RETURN

jacks on the rear panel.)

The Distortion effects of the GW33 are made up of both

analog and digital distortion circuits, giving you excep-

tional quality and flexibility in creating distortion sounds.

Effect Type Settings: 1 – 12

The Distortion types are shown below. Also shown are

the Pre-drive and Drive parameters (where applicable) and

the signal path.

Types 1 – 5

These types feature two distortion circuits, the first

controlled with the Pre-drive parameter and the second

with the Drive parameter. The first three types are a

combination of digital and analog distortion, letting you

blend just the right amount of digital “bite” and analog

warmth in your distortion effects.

(This parameter is not available in Type 12.)

NOTE ■

If the Pre-drive and Drive parameters are both

set to near the maximum, the resulting noise may be so

excessive that even the Noise Gate has no effect in

cleaning up the signal.

HINT ■

The Level parameter should be set to an appro-

priate value to avoid sudden jumps or drops in level when

switching the Distortion block on and off.

The EQ/AMP block provides an Equalizer effect and three

different Amp Simulator effects.

Effect Type Settings: 1 – 4

The Equalizer/Amp Simulator types are shown below.

Types 2, 3 and 4 are Amp Simulator effects.

1 Equalizer

2 Stack

3 Combo

4 Tube

Type 1 Equalizer

The Equalizer is a three-band graphic type that gives you

fine tone control over the sound.

Low Range: -7 – 7

Determines the amount of boost or cut applied to the low

frequencies.

Mid Range: -7 – 7

Determines the amount of boost or cut applied to the

midrange frequencies.

High Range: -7 – 7

Determines the amount of boost or cut applied to the high

frequencies.

Level Range: 0 – 15

Determines the level of the Equalizer effect.

HINT 1 ■

Take care when using maximum levels;

distortion could result, especially when all parameters are

set to around the maximum.

HINT 2 ■

The Level parameter of these types should be

set to an appropriate value to avoid sudden jumps or

drops in level when switching the EQ/AMP block on and

off.

Equalizer/Amp Simulator (EQ/AMP) Block

Types 2 – 4 Amp Simulator

The Amp Simulator effect types realistically reproduce the

characteristic sound of a guitar amplifier, and provide a

natural sound for recording when not using an external

amplifier. When using an amplifier, they also provide a

convenient way to change the sound characteristics of

your amplifier. These are also particularly effective when

used with one of the Distortion effects.

Three different types of cabinet sound are available: Stack,

Combo and Tube.

Stack (Type 2) recreates the powerful sound of a huge

amp/speaker setup, Combo (Type 3) recreates a compact

amp cabinet, and Tube (Type 4) recreates the warm sound

of a tube amplifier.

Modulation (MOD) 1 and 2 Blocks

The Modulation blocks feature a wide range of modulation

and pitch change effects, including Chorus, Flanger,

Phaser, Pitch Shift and Detune. Exciter, Touch Wah and

Pedal Wah effects are also available. Modulation 1 and 2

have the same set of effects, and since each block is

independent, two different Modulation effects can be used

at the same time.

All Modulation effects, excepting Pitch Shift, Exciter,

Touch Wah and Pedal Wah, are in stereo. (However,

Pitch Shift can be used in stereo if both blocks are set to

that effect.)

Effect Type Settings: 1 – 8

1 Chorus

2 Flanger

3 Phaser

4 Pitch Shift

Type 1 Chorus

Chorus uses modulation of the pitch and separation of the

signal into stereo to greatly enhance the sound, generally

making it richer, fatter and warmer.

Speed Range: 1 – 16

Determines the speed of the pitch modulation. The higher

the value, the greater the speed.

Depth Range: 1 – 16

Determines the depth of the pitch modulation, or how

widely the pitch is varied. The higher the value, the

greater the pitch depth.

Tone Range: -7 – 7

Determines the degree to which high frequencies are cut

or boosted. Lower values decrease the high frequencies,

and higher values boost them.

On/Off (Switch 4) Settings: 1 – 3

Determines how Pedal Switch 4 affects on/off switching

for the Modulation 1/2 blocks.

Settings:

1 (Effect Off)

This leaves the selected block (Modulation 1 or 2)

always off, no matter if Pedal Switch 4 is pressed or

not.

2 (Effect On)

This leaves the selected block (Modulation 1 or 2)

always on, no matter if Pedal Switch 4 is pressed or

not.

3 (Switch)

This enables on/off switching of the selected block

(Modulation 1 or 2) with Pedal Switch 4.

Type 2 Flanger

Flanger is a stereo effect that uses modulation to create an

animated, swirling motion effect. It is effective in empha-

sizing the metallic sound of a guitar.

Speed Range: 1 – 16

Determines the speed of the pitch modulation. The higher

the value, the greater the speed.

Depth Range: 1 – 16

Determines the depth of the pitch modulation, or how

widely the pitch is varied. The higher the value, the

greater the pitch depth.

Feedback Range: 0 – 15

Determines the amount of the Flanger-processed signal

that is fed back to the Flanger input. Higher values result

in stronger, more pronounced flanging.

On/Off (Switch 4) Settings: 1 – 3

Determines how Pedal Switch 4 affects on/off switching

for the selected Modulation block. (For more information,

see the same parameter in the Chorus section above.)

Type 3 Phaser

The stereo Phaser effect is similar to the sound of a rotary

speaker, but with a stronger and deeper modulation.

Speed Range: 1 – 16

Determines the speed of the phase modulation. Settings

close to the maximum produce very high speed modula-

tion.

Depth Range: 1 – 16

Determines the depth of the phase modulation, or how

widely the pitch is varied.

Feedback Range: 0 – 15

Determines the amount of the Phaser-processed signal that

is fed back to the Phaser input. Higher values result in a

stronger, more pronounced phasing sound.

On/Off (Switch 4) Settings: 1 – 3

Determines how Pedal Switch 4 affects on/off switching

for the selected Modulation block. (For more information,

see the same parameter in the Chorus section above.)

Type 4 Pitch Shift

Pitch Shift lets you change the pitch of the sound and mix

the pitch-shifted sound with the original signal. The pitch

can be shifted up to an octave above or below the pitch of

the input signal.

When both the Modulation 1 and 2 blocks are set to Pitch

Shift, the effect is automatically produced in stereo. This

means that the degree of pitch shift can be set indepen-

dently for the left and right channels, creating three

separate pitches (including the original direct signal).

When set to stereo operation, Modulation 1 is output from

the left channel and Modulation 2 from the right.

Applications for Pitch Shift include setting the pitch shift

to an octave below or above (to make a six-string guitar

sound like a twelve-string), or setting the pitch to other

intervals (such as a fourth or fifth) to create instant harmo-

nies and fill out the sound.

Pitch Settings: -8 – 8

Determines the amount by which the pitch is shifted

relative to the original signal.

The illustration below shows the relationship between the

settings and the actual pitch produced. The example

pitches below are produced when the input sound is C.

—

(No parameter for this Parameter Dial.)

Mix Range: 0 – 15

Determines the level of the Pitch Shift sound. At 0, the

Pitch Shift level is zero; at 15, the level of the Pitch Shift

sound is roughly equal to that of the original signal.

On/Off (Switch 4) Settings: 1 – 3

Determines how Pedal Switch 4 affects on/off switching

for the selected Modulation block. (For more information,

see the same parameter in the Chorus section above.)

Type 5 Detune

Detune, like Pitch Shift, allows you to change the pitch of

the sound. However, it gives you finer control, letting you

shift the pitch slightly. It is also a stereo effect. Detune is

good for creating a natural, spacious stereo chorus effect

in which the left and right pitches are detuned slightly

relative to the direct sound.

Pitch L (Left) Range: -8 – 8

Determines the degree of detuning for the left channel.

Settings:

±1: ±2 cents ±5: ±10 cents

±2: ±4 cents ±6: ±20 cents

±3: ±6 cents ±7: ±30 cents

±4: ±8 cents ±8: ±50 cents

* Fifty cents is equal to 1/2 of one semitone (half-

step).

is roughly equal to that of the original signal.

On/Off (Switch 4) Settings: 1 – 3

Determines how Pedal Switch 4 affects on/off switching

for the selected Modulation block. (See page 24.)

Type 6 AURAL EXCITER

The Exciter effect enhances the sound by giving it greater

definition and clarity. Generally used with the Distortion

effect off, it adds sparkle and presence to the sound. It is

especially effective when used in tandem with the Amp

Simulator effect. With Distortion on, it functions much

like an equalizer.

Enhance Range: 0 – 15

Determines the degree or depth of the Exciter effect. If

this is set to 0, there is no Exciter processing, and the other

parameters have no effect on the sound.

Frequency Range: 1 – 16

Determines the center frequency for the Exciter effect.

Maximum values emphasize the high frequencies, while

minimum values emphasize the low frequencies.

Mix Range: 0 – 15

Determines the level of the Exciter sound. At 0, the

Exciter level is zero; at 15, the level of the Exciter sound

is roughly equal to that of the original signal.

On/Off (Switch 4) Settings: 1 – 3

Determines how Pedal Switch 4 affects on/off switching

for the selected Modulation block. (See page 24.)

Type 7 Touch Wah

Type 8 Pedal Wah

Wah is a filter sweep effect that, as its name implies,

produces a “wah” type sound. Two different Wah effects

are available: Touch and Pedal. Touch lets you vary the

sweep of the filter according to the input level (how hard

or loud you play) while Pedal lets you “play” the Wah

effect with a connected Foot Controller.

NOTE ■

When Touch Wah or Pedal Wah is selected, the

Modulation block using Wah is placed first in the effect

chain, just before the Compressor. (See page 7.)

Touch Wah

The Touch type lets you control the Wah effect by the

level of the input signal (or how hard you play). In

Touch, the filter sweep (or “wah” sound) starts at the

beginning each time it is triggered.

Pedal Wah

Pedal Wah lets you sweep the filter manually with a

connected Yamaha FC7 Foot Controller. When Pedal

Wah is selected and the block is on, volume control

with the Foot Controller is automatically disabled. (See

page 30.) When the Foot Controller is disconnected,

the Pedal Wah effect automatically is set to the center

frequency.

Sense (Touch Wah only) Range: 1 – 16

Determines how sensitive the Wah effect is to the instru-

ment input. The higher the value, the more sensitive the

trigger of the Wah effect becomes to low level signals;

even with a low level input, the band pass filter of the

Wah effect is applied.

HINT ■

For best results, when playing a solo or a line, try

setting Sense to a high value; when performing backing

or rhythm parts, try setting Sense to a low value. (This is

because playing a single string results in a lower level

than playing all six strings.)

Frequency Range: 1 – 16

Determines the center frequency of the Wah effect. The

Wah effect sweeps this frequency over the frequency

range set in the Range parameter.

Range Range: 0 – 15

Determines the width of the frequency sweep, or how far

the sweep extends above and below the center frequency.

Higher values create a more pronounced “wah” sound.

On/Off (Switch 4) Settings: 1 – 3

Determines how Pedal Switch 4 affects on/off switching

for the selected Modulation block. (See page 24.)

The Delay effect allows you to add delayed, echo-like

repeats to the original sound. Subtle use of Delay helps in

creating a sense of space and depth in the sound. Delay

can also be used for special applications, such as creating

rhythmic repeats in the sound.

NOTE ■

Since Delay is a mono effect, it is placed just

before the Modulation 1/2 blocks in the effect chain. (See

page 7.)

HINT ■

One convenient function of the GW33 is that it

lets you change between effect programs having similar

Delay settings without cutting off the delay sound. To

take advantage of this, the Delay Time parameters of the

respective programs must be set to the same value.

Even if the programs change from Delay ON to Delay

OFF, setting the same value for the Delay Time param-

eters will make the transition sound smoother.

NOTE ■

Keep in mind that when you change between

effect programs having similar Delay settings, the con-

tinuing Delay sound from the previous program will be

processed with the other effect blocks of the new pro-

gram. For example, when changing from program “A” (in

which Mix is set to 0) to program “B” (in which Mix is at or

near the maximum), the Delay sound will suddenly jump

in level.

Time Range: 10 – 90 (10 – 90 msec),

10. – 81. (100 – 810 msec)

Determines the time between delayed repeats of the main

delay. Very short delays make it possible to make one

instrument sound like two separate instruments. Slightly

longer delays can be used for creating slap-back echo or a

reverb-type effect. Longer times are used for special

effects, like creating long echoes or steady rhythmic

pulses. Since the BANK/MEMORY indicator only has

two digits, Delay Times of 100 or over are indicated by

the dot in the display. (The dot represents the final zero in

the value.)

Delay Block

Feedback Range: 1 – 16

Determines the number of the delayed repeats. Lower

settings result in a single repeat or a few repeats, while

settings toward the maximum result in the repeats carrying

on almost indefinitely. The repeat sounds gradually decay

to silence, and the time it takes for them to decay is also

controlled by Feedback.

Mix Range: 0 – 15

Determines the level of the Delay sound. At 0, the Delay

level is zero; at 13, the level of the Delay sound is roughly

equal to that of the original signal.

On/Off (Switch 5) Settings: 1 – 3

Determines how Pedal Switch 5 affects on/off switching

for the Delay block.

Settings:

1 (Effect Off)

This leaves the selected block (Delay or Reverb)

always off, no matter if Pedal Switch 5 is pressed or

not.

2 (Effect On)

This leaves the selected block (Delay or Reverb)

always on, no matter if Pedal Switch 5 is pressed or

not.

3 (Switch)

This enables on/off switching of the selected block

(Delay or Reverb) with Pedal Switch 5.

Reverb is an important effect in the guitarist’s sonic

palette. Without it, the sound is flat, dry and unnatural.

Used judiciously, it is an effective way to bring the sound

to life and make it sound more natural. Reverb comes last

in the effect chain, since it is used to reproduce the ambi-

ence that follows a sound when heard in an actual perfor-

mance environment. Four different Reverb types are

available: Hall, Room, Stage and Plate.

HINT ■

One convenient function of the GW33 is that it

lets you change between effect programs having similar

Reverb settings without cutting off the Reverb sound. To

take advantage of this, the Reverb Type parameters of

the respective programs must be set to the same value.

NOTE ■

Keep in mind that when you change between

effect programs having similar Reverb settings, the

continuing Reverb sound from the previous program will

be processed with the other effect blocks of the new

program. For example, when changing from program “A”

(in which Mix is set to 0) to program “B” (in which Mix is at

or near the maximum), the Reverb sound will suddenly

jump in level.

Reverb Block

Type Settings: 1 – 4

Determines the type of simulated reverb environment.

Hall (1) recreates a concert hall sound, Room (2) simulates

a smaller performance environment, Stage (3) features a

bright and “live” reverberation, and Plate (4) reproduces

the warm sound of plate reverb.

Time Range: 1 – 16

Determines the time it takes for the reverberation to decay.

Higher values create a larger apparent room size.

Tone Range: 1 – 10

Determines the sound quality of the Reverb. Lower values

decrease the brightness, and higher values increase it,

creating a more “live” room sound.

Mix Range: 0 – 15

Determines the level of the Reverb sound. At 0, the

Reverb level is zero; at 15, the level of the Reverb sound

is roughly equal to that of the original signal.

On/Off (Switch 5) Settings: 1 – 3

Determines how Pedal Switch 5 affects on/off switching

for the Reverb block. (For more information, see the same

Noise Gate is a separate effect that is placed just after the

Distortion block, and is used to eliminate any noise or

hum in the signal when the instrument isn’t being played.

All signals below the Threshold point are filtered out, thus

cutting off the noise.

—

(No parameter for this Parameter Dial.)

Threshold Range: 0 – 15

Determines the sensitivity of the noise gate, or how loud

an input signal is required to open the gate (letting the

signal through).

The higher the Threshold value, the louder the signal

needs to be to open the gate. For optimum operation,

Threshold should be set just above the level of the noise;

setting it too high may cause notes to be cut off too

abruptly. Setting it too low, however, will result in little

or no effect. (At a value of 0, the Noise Gate is not

applied.)

An optional FC7 Foot Controller can be connected to the GW33 for use as a volume pedal or as a

realtime controller for the Pedal Wah effect. When used as a volume pedal, it can be placed in

one of four positions in the effect chain, and be given a Minimum Volume setting (for when you

need to easily change between two different volume settings).

The connected Foot Controller can also be used to con-

tinuously change the sound of the Pedal Wah effect. To

do this, simply select the Pedal Wah type for the Modula-

tion 1 and/or Modulation 2 blocks, and make sure that the

effect is properly turned on. (For more information on

using Pedal Wah and the Foot Controller, see page 26.)

Using the Foot Controller for Pedal Wah Control

NOTE ■

When Pedal Wah control is enabled in this way,

Volume control with the Foot Controller is automatically

disabled.

Setting the Volume Position and Minimum Volume

OPERATION

Enable the Edit mode (press the e

button), and select the Noise Gate/Utility block.

Change the desired Foot Controller parameter

value with the corresponding Parameter Dial: C or

Parameter Dial C controls Volume Position and D

controls Minimum Volume. (Parameter Dial B

applies only to the Noise Gate effect; see page 29.)

Volume Position

Determines the point in the effect chain at which the

volume pedal control is placed.

Settings:

1: Before the Distortion/Insert block (q)

2: Before the Delay block (w)

3: Before the Reverb block (e)

4: After the Reverb block (r)

Minimum Volume

Determines the level that is output when the connected

Foot Controller is at the minimum position. (Range: 0 –

15)

Minimum Volume can be set to a level somewhere be-

tween no sound at all and maximum volume, letting you

use the Foot Controller to easily move between two

volume settings. For example, if you set the Minimum

Volume to a level somewhat less than maximum, you can

instantly change from a solo level to a backing level by

bringing the Foot Controller up to the minimum position.

any order you wish, or put programs that are often used together in the same bank, so that you

can call up the right effect programs quickly and easily onstage or in the studio.

Copying One Effect Program to Another Program Number

The Copy operation copies the settings of one program

number to another program number. The program at the

destination is erased and replaced with the copy.

OPERATION

With the Play mode enabled, select the source

program (the effect program to be copied).

Press the c button. (The COPY lamp lights,

and the BANK/MEMORY indicator flashes.)

Use Parameter Dial A to select the destination

program number.

To actually copy the program to the destination

number, press the y button. To cancel the

operation, press the n button.

NOTE ■

User pro-

grams can only be

copied to other User

program numbers.

Preset programs can

be copied to any

program number, User

or Preset.

CAUTION! ■

Keep in mind that when you copy a

program to another number, the program at the

destination number is erased. (However, you can

restore any erased programs; see page 33 for de-

tails.)

HINT ■

If you do any appreciable amount of copying and

swapping of programs, you may soon lose track of which

program is at which number and which programs have

been erased. For this reason, you should carefully plan

how you intend to reorder the programs and keep a

written record of copy and swap operations you’ve

performed.

If you’ve erased one or more of the effect programs by

replacing it with one of your own creation, you can use

this function to restore the original program or pro-

grams.

NOTE ■

Remember that restoring a Preset program

will irretrievably erase whatever effect that you

created and saved to the corresponding effect

program number. For this reason, you should always

make a written record of the settings you make (using

a copy of the Blank Effect Parameter Chart on page

38), so that you can reprogram the effect later if

necessary.

Restoring Factory-set Effect Programs

The Tuner function allows you to quickly and accurately tune your guitar without having to

disconnect it from the GW33. It also temporarily cuts off the sound, so that you can tune it

silently and inconspicuously during a performance.

Tuning the Pitch of the Connected Instrument

OPERATION

While in the Play mode, press the t button.

Alternately, simultaneously press and hold down

Pedal Switches 1 and 2 together for a second or

two, and release them. (All lamps of the GW33 go

out).

The string number and note name appear in the

BANK/MEMORY indicator. Accidentals (sharps)

are indicated by the lit Sharp (#) lamp. How close the

note is to being in tune is indicated by the five middle

Effect Block/Tuner lamps, as shown below.

Let the note ring out consistently, and tune the

instrument so that the center indicator flashes.

Continue with other notes (the other strings on

your guitar) until the instrument is in tune.

Exit from the Tuner function by pressing the

t button again.

You can also exit by pressing any of the Pedal

Switches (1 – 5, B) or the p button.

Changing the Standard Pitch of the Tuner Function

The default standard pitch setting of the Tuner (when

power is turned on) is A = 440 Hz. However, this can be

raised to as high as A = 445 Hz (in 1-Hz steps).

To change the standard pitch, use Parameter Dial A.

The built-in Metronome function supplies an audio click (output through the rear panel outputs)

for practice purposes. The time signature, tempo and level of the click are all adjustable.

(No parameter for this Parameter Dial.)

Beat Settings: 1/4 – 8/4, 1/8 – 8/8

Determines the time signature of the Metronome. The

first digit in the display indicates the top number of the

time signature (the number of beats in a bar), while the

second digit indicates the bottom number (the kind of note

used for the beat). For example, “34” in the display

indicates a time signature of 3/4.

HINT ■

You can automatically double the speed of the

tempo by setting the Beat value to a “double” denomina-

tor. For example, when Beat is set to 4/4, you can double

the tempo by setting it to 4/8.

Tempo Range: 60 – 186 (86.)

Determines the tempo, or speed, of the Metronome (in

even-numbered values). Tempo values of 100 or greater

are represented by a dot in the display.

Click Level Settings: 1 Lo, 2 Mid, 3 Hi

Determines the level of the click sound.

Set the desired time signature, tempo, and level

values with Parameter Dials C, D and E.

APPENDIX

Even though the GW33 is exceptionally easy to use, it may occasionally not function as you

expect it to. Note that the problems covered here are not malfunctions of the GW33.

PROBLEM POSSIBLE CAUSE AND SOLUTION

The instrument (guitar) sound

cannot be heard.

No sound is output, even when

Bypass is on.

Sound can only be heard when

Bypass is on.

The effect processing cannot be

heard.

The Pedal Switches cannot be

used to turn effect blocks on and

off.

Even when adjusting the param-

eter value, there is no change in

the sound.

Even though Distortion is off, the

sound is distorted.

• Check that all connections have been properly made and that all levels have

been appropriately set (including the Foot Controller, if you are using one).

• Make sure that the Tuner is not active.

• Check the volume controls on your guitar and amplifier.

• Check all connections, including your guitar cord, amplifier cords and head-

phones.

• Is the Total Volume set to 0?

• Is the Foot Controller set to the minimum position?

since this calls up the Write operation.

• Make sure that the Play mode is active.

• Make sure that you press both the c and s buttons simulta-

neously.

• Make sure that the Play mode is turned on.

There is too much noise in the

sound or the sound is unexpect-

edly distorted.

changed, the Delay or Reverb

sound continues.

The Pedal Wah effect doesn’t

work.

The Volume pedal control doesn’t

work.

The Copy operation cannot be

used, even when the c button

is pressed.

The Swap operation cannot be

used, even when the s

button is pressed.
