The GW33 is a portable and convenient multi-effect device designed especially for guitar. The comprehensive 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 Simulator, 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.
HOWTOUSETHISMANUAL
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 understand its various functions and use the device to its full
potential.
To actually start using the GW33, read the
(page 10). It guides you step-by-step in setting up

your GW33, connecting it properly, and (most importantly!) getting sound out of it. The section also introduces 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.

HOW TO USE THIS MANUAL (READ THIS FIRST!!) . . . . . . . . . . . . . . . . . . . . . . 1
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 usethe PA-3B.) Also make sure that the adaptor you have is
■ 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.
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 sturdiness 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 disconnecting 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.
■ 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.

The Effects 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. Moreover, 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 simultaneously, 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 undesirable noise. (See page 29.)
(Same as Modulation 1; effects can be used
independently.)

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 parameters, 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.

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

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

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

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 Simulator effect, changes to which are easier to hear when
Distortion is also on.)

HINT 1 ■
When editing an effect, make sure that the
Level or Mix parameters of the effect are set to
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 ANDPARAMETERS on page 20.
HINT 2 ■
If you are using the optional FC7 Foot
Controller, try experimenting with the Foot Controllerrelated Volume Position, Minimum Volume and Total
Level parameters in the Noise Gate/Utility block. (See
FOOT CONTROLLER OPERATIONS on page 30.)
5
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.)
EDIT/
COMPARE
Each press of the e button switches back
and forth between the original program (lamp flashes)
and your new edits (lamp lights continuously).
While the EDIT/COMPARE lamp is flashing (Compare mode), you can hear the sound of the original
effect program. You can also view the original parameter values: simply select the desired effect block with
the y and n buttons and turn the Parameter Dials. Values cannot be changed in this condition;
they are only displayed so that you can compare them
with values you’ve edited.
EDIT/

■ 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.)
