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 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.

PR E C A U T IO N S

■ 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 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.

■ 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 equipment.

PA N E L C O N T R O L SA N D T E R M IN A L S

This section shows and explains all of the controls and terminals of the GW33. Since the explanations below are fairly brief, you should turn to the page references given for more information on individual buttons and features.

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.)

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.

These are used to change the parameters in the corresponding columns.

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.

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.

When using a single guitar amp, connect to

the L/MONO OUTPUT jack.

Signals are output through

the OUTPUT jacks, even when headphones are connected.

Adjust the headphone volume with the Total Level parameter (see page 31).

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).

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.

Firmly press and hold these down for about one second.

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.

Now that you’ve set up your GW33 and have got sound out of it, let’s try playing with some of the effects. (If you haven’t already done so, read through the GW33 SYSTEM OVERVIEW section on page 7 for information on the basic structure of the GW33.)

First, make sure that the Play mode is enabled. Press p.
