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.

HOWTOUSETHISMANUAL

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

TOUR

GUIDED

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.

( READ THIS FIRST!!)

REFERENCE

The

(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
is also mainly for reference. In general, look through this
section to familiarize yourself with the controls, and refer
to it when necessary.

The

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.

of the GW33, tips on troubleshooting (when something
doesn’t work as expected), and other important informa­tion.

■ 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

■ 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.
