Congratulations and thank you for purchasing the Yamaha GW50 Guitar Performance Effector. The GW50 combines high-quality multi effects for guitar (and other instruments as well) with a sophisticated backing section that provides realistic automatic rhythmic accompaniment for you to play along with. The dual functions — effects and backing — make the GW50 useful in a wide range of applications, from live performance and studio use to home recording and individual music practice.

Some of the advanced features of the GW50 include:

Effect Section

■Five basic effect blocks, featuring Compressor, Distortion, Equalizer, Chorus and Reverb/ Delay, plus additional effect types within each block, such as Overdrive, Wah, Amp Simulator, Flanger, Phaser, Pitch Shifter, Tap Delay, and a built-in Noise Gate.

■User memory for storing up to 50 user-created effect programs, all instantly selectable from the convenient Pedal Switches. (See pages 11, 25.)

■High-quality sound in all effects, plus added sonic benefit of having all effects integrated into one unit.

■Comprehensive parameter control over all effects, yet exceptional ease-of-use — you can adjust the main parameters of the effect blocks just as you would on conventional pedal effects.

Backing Section

■A total of 248 automatic rhythm and accompaniment patterns, using realistic drum, bass and other backing instrument sounds. (See page 32.) The automatic accompaniment includes sophisticated chord control, with 25 different chord types available in all keys. (See pages 33-35.)

■Song record capability, for creating songs with the rhythm/accompaniment patterns and chord changes, as well as automating effect program changes, effect bypass and other functions. (See pages 36-38.)

■A special Root Select function (see page 78), which lets you change the root note of the backing chord by playing the note on your guitar, and Triggered Run (see page 82), which allows you to start a song or pattern just by playing a note on your guitar.

Other Features

■Convenient Pedal Switch control over many functions, including chord change, start/stop of pattern/song playback, bypassing of effects, and so on.

■Built-in tuner, allowing you to tune your instrument without removing it from the signal chain. (See page 39.)

■Various MIDI features for interfacing with a wide range of other MIDI devices. (See pages 101-107.)

PRECAUTIONS

PRECAUTIONS

■USE THE CORRECT POWER SUPPLY

Power to the GW50 should be supplied only from the appropriate Yamaha AC adaptor (the included PA-3). Use of another adaptor may cause serious damage to the unit. 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 GW50. (The correct input voltage is marked on the adaptor.)

■USE ONLY APPROPRIATE FOOT CONTROLLERS AND FOOTSWITCHES

Certain functions of the GW50 can be controlled by the optional Yamaha FC7 Foot Controller and the FC5 (or FC4) Footswitch. Use of any other pedal or footswitch besides those recommended here may result in erratic operation or may cause some other trouble in the foot controller or footswitch itself.

■ MEMORY BACKUP

The GW50 memorizes the following data, even when the power is turned off: Memory effect program data, Manual effect data (excepting main parameter values), song data, and general panel settings. The GW50 contains a special long-life lithium battery that retains this data in the internal RAM memory. The battery should last for approximately five years from the date of manufacture. When the backup battery power becomes too low to maintain the memory contents, a warning message appears in the LCD:

(This message appears only when the power is turned on, and stays in the LCD until a panel button is pressed.) When this happens, save all original data to a MIDI data storage device (see note below) or write down all necessary settings to a piece of paper, then have the battery replaced by qualified Yamaha service personnel as soon as possible. DO NOT ATTEMPT TO REPLACE THE BACKUP BATTERY YOURSELF!

BACKING UP DATA—We recommend that you transfer all important data to a MIDI data re- IMPORTANT corder, such as the Yamaha MDF2 MIDI Data Filer or another data storage device, for safe, longterm storage. (For more information, refer to the section on the MIDI Bulk Dump function, page 102.) Yamaha cannot be held responsible for data loss caused by battery failure or improper

operation of the GW50.

■ AVOID PHYSICAL SHOCKS

Although the GW50 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 GW50 is a preci- sion-made electronic device, also avoid applying excessive force to the various controls. Also, avoid stepping on any part of the GW50 other than the Pedal Switches, since this may damage or break the controls or glass of the display.

ii PRECAUTIONS

PRECAUTIONS

■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.

■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 MAKING 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 cloth slightly moistened with a diluted, mild detergent — making sure to wipe the case off again with a dry cloth.

■ ELECTRICAL INTERFERENCE

Since the GW50 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 GW50 further away from the affected equipment.

■ MIDI CABLES

When connecting the GW50 to other MIDI equipment, be sure to use only high-quality cables made especially for MIDI data transmission. Also avoid cables longer than 15 meters, since long cables can result in data errors.

HOW TO USE THIS MANUAL (READ THIS FIRST!)

HOW TO USE THIS MANUAL (READ THIS FIRST!!)

You are probably eager to try out your new GW50 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. This tells you briefly how to care for your new GW50, how to avoid damaging it, and how to ensure long-term, reliable operation.

Next, read through the section The GW50: WHAT IT IS AND WHAT IT CAN DO.

This briefly gives you an overview of the functions of the GW50 and how you can use it effectively.

The bulk of the manual has been organized into two parts: the GUIDED TOUR (TUTORIAL) and the REFERENCE section.

Read the GUIDED TOUR (TUTORIAL) next. It guides you step-by-step in setting up your GW50, connecting it properly, and (most importantly!) getting sound out of it. The section also goes on to take you through some of the more important functions of the GW50, explaining by way of example how to use it.

The REFERENCE section, 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 is also mainly for reference. However, you should read through the parts here concerning the Pedal Switches, since these are particularly useful and convenient in operating the GW50. In general, look through this section to familiarize yourself with the controls, and refer to it when necessary.

The INDEX in the APPENDICES sections at the back of this manual is also very helpful. It lists and gives page numbers for virtually every function, feature, control and terminal found on the GW50, and gives you a quick, easy way to find what you’re looking for.

Other parts of the APPENDICES and SUPPLEMENTAL INFORMATION sections provide additional useful information: lists of all effect programs, patterns and songs of the GW50, a list of error messages, tips on troubleshooting (when something doesn’t work as expected), and other important information.

HOW TO USE THIS MANUAL (READ THIS FIRST!!) 1

THE GW50: WHAT IT IS AND WHAT IT CAN DO

THE GW50: WHAT IT IS AND WHAT IT CAN DO

WHAT IT IS …

Effect and Backing Sections

The GW50 is actually two different devices in one.

On the one hand, it has an Effect section which provides high-quality and easy-to-use multi effects designed especially for processing electric guitar.

On the other, it has a Backing section which provides realistic automatic rhythm, chord and bass patterns for creating your own accompaniment. Moreover, the GW50 includes a built-in tuner for tuning your instrument without having to remove it from the effect chain.

The Effect section has two mode groups: Manual, which lets you use the GW50 effects just as would a normal pedal effect unit, and Memory, which lets you call up preset effect programs and create your own original programs.

The Backing section also has two mode groups: Pattern, which lets you play the various rhythm patterns, and Song, which lets you play pre-pro- grammed songs and create your own original songs.

Modes of the GW50

The tree chart on the next page shows the relationships of the various modes of the GW50. There are four main modes — Manual, Memory, Pattern and Song — indicated by the shaded areas. All other modes are either separate from them (as with Tuner, MIDI Bulk Transmission and Demo) or are subordinate to them.

The Effect and Backing sections are active simultaneously; however, when making adjustments or performing certain operations within a mode in one of the sections, generally you should press the desired mode button ([MANUAL], [MEMORY] or [SONG/PATTERN]) to make sure that the mode is properly called up before attempting the operation.

Functions in Each Mode

Specific functions and operations of the various modes include:

Manual: Changing the parameters of the effects. Manual Job: Storing parameter settings to a pro-

gram.

Memory: Selecting and using an effect program. Memory Edit: Changing the parameters of an

effect program.

Memory Edit Compare: Comparing the sound and values of edited program with the

original.

Memory Job: Copying, swapping and naming effect programs.

Pattern: Playing the patterns of the Backing section.

Song: Playing a song, or using the Step Recording features to edit a song.

Song Realtime Recording: Recording events to a song in realtime.

Song Job: Copying or deleting measures within a song; naming a song.

Keep in mind as you read this manual that the phrase “main modes” refers to the Manual, Memory, Pattern and Song modes, and that “mode buttons” refers to the [MANUAL],

[MEMORY] and [SONG/PATTERN] buttons.

THE GW50: WHAT IT IS AND WHAT IT CAN DO

The illustration below shows how the Pattern mode and Song mode are used.

Pattern Mode

In the Pattern mode, individual patterns are played back and repeated.

(for examples, 2 measures)

Song Mode

In the Song mode, the preset patterns can be strung together to create a song. Other events, such as chord changes and muting events, can also be entered.

WHAT IT CAN DO …

Here are a few ideas on how you can use your GW50. The list below is in no way comprehensive, but is meant to be a starting point or springboard for your own creative ideas and explorations.

■ All-in-one	effect unit for
on the stage, in the
studio, or	in rehearsal

With its five effect blocks, the GW50 has all you need to augment your sound, whatever the application. Any or all five effects can be used in virtually any combination as an effect program, and you can instantly select from 50 different effect programs as you play. Plus, flexible effect bypass (on/off) functions give you even more real time control over the sound.

■ Convenient practice tool

The rhythm, bass and accompaniment patterns of the GW50 are perfect for playing along with. By stringing together the rhythm patterns and recording chord changes, you can create and playback complete songs over which you can practice.

Having the full accompaniment behind you is a much more inspiring and exciting way of practicing than using just a metronome.

■Sketchpad for composing and arranging

The accompaniment features can also be used to help you flesh out your own musical ideas. With the wealth of chords (a total of 25 different chord types for each of the 12 keys) and the convenient editing features, the GW50 makes it exceptionally easy to quickly turn your inspirations into complete songs. Plus, the extraordinarily realistic sounds give you the tools to present polished versions of your ideas to others.

Now that you have a basic idea of how the GW50 can help you in your music, go on to the GUIDED TOUR (TUTORIAL), and learn how to set up and use your GW50.

4 THE GW50: WHAT IT IS AND WHAT IT CAN DO

PANEL CONTROLS AND TERMINALS

PANEL CONTROLS AND TERMINALS

This section shows and explains all of the controls and terminals of the GW50. Since the explanations below are fairly brief, you should turn to the page references given for more information on individual buttons and features.

A few general comments:

■Some of the buttons described below must be pressed together to call up a certain function. These are indicated either by a “ +” mark (for example, “ [SHIFT] + [SUB PARAM]”), or by the word “with” (for example, “With

[SHIFT]:”).

■Markings for three of the panel controls which

are used simultaneously with another control — SHIFT , CHORD and B (for the ASSIGN-

ABLE Block Pedal Switch) — are enclosed in a border which indicates the direction(s) in which their companion controls can be found. For example, the CHORD mark points to the right, indicating that the settings below the buttons on the right can be selected by simultaneously pressing CHORD and the appropriate button.

■Also, keep in mind that the function which is enabled — simultaneously holding down

SHIFT , CHORD or	B , and pressing that
button — is always printed	below the button.

■The buttons whose primary functions are indicated in boxed titles above each button ([MANUAL], [MEMORY] and [SONG/PATTERN]) are referred to as the “mode buttons” and can be conveniently used as exit buttons to “escape” from most in-progress operations (such as Copying, Naming, MIDI Bulk Transmission, etc.).

■All controls that are used to increase or decrease values feature continuous and rapid operation, to let you more quickly and easily reach a desired value. With the [–]/[+] buttons, hold down one button to continuously move through the values and, while holding down that button, press the other to increase the speed. Releasing the second button returns to normal speed. With Pedal Switches 1 and 2 (when used for [–]/[+] control) and the Position Control buttons (<, >, etc.), holding down the appropriate control moves through the values with increasing speed.

GUIDED TOUR (TUTORIAL)

SETTING UP AND PLAYING YOUR GW50

Once you’ve taken your GW50 out of the box and are ready to use it, follow the simple instructions below in making the connections and setting it up.

1. First, make sure that the power switch on the GW50 is off before making ANY connections.

2. Plug the DC output cable from the supplied PA-3 adaptor into the DC IN terminal on the rear panel, then plug the adaptor into a convenient AC outlet.

DC IN Cable clip (see page 15).

Note: Be sure to check whether the rated voltage is appropriate. The provided adaptor is intended for use in the area which you purchased the GW50. If you intend to use it in a different area, consult your Yamaha dealer for more information on voltage requirements.

Do not attempt to use a different AC adaptor with the GW50. The use of an incompat- CAUTION ible adaptor may cause irreparable damage to the unit and pose a serious shock hazard.

3. Plug your instrument into the INPUT jack on the rear panel.

INPUT

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; generally their output level is much higher than that of a guitar and the input level (see step #6 below) should be turned down accordingly.

Do not connect the BACKING/MONO output jack with the INPUT jack in an attempt to CAUTION use the effects of the GW50 on the Backing

sound. Doing so results in feedback.

4. Connect the GW50 outputs to your amplifier/ speaker system, making sure that the power on the system is first turned off.

Four example connection systems are shown below. Use the one which most closely resembles your own system.

Note:When using Distortion on the GW50, use the clean channel of the guitar amp.

SETTING UP AND PLAYING YOUR GW50 19

GUIDED TOUR (TUTORIAL)

Example 1 — One Input

In this system, a guitar amp with only one input is used. Since the Backing sound and instrument/effect sound are output together, adjust the balance between the two with the rear panel BACKING LEVEL control.

Example 2 — Two Inputs

In this system, a guitar amp with two inputs is used. The balance between the instrument/effect output and the Backing sound can be adjusted on the amp.

Example 3 — Guitar Amp(s) and Stereo System

In examples 2, 3 and 4 above, only the Backing parts (rhythm, accompaniment, etc.) are output from the BACKING/MONO jack and only the instrument/effect sound is output from the L/L + R jack or the L/L + R and R jacks.

You can also listen to the GW50 through a set of headphones. Connect them to the PHONES jack on the rear panel.

5. If you have them, connect a foot controller (the optional Yamaha FC7) to the FOOT CONTROLLER jack, and a footswitch (the optional Yamaha FC5 or FC4) to the FOOT SW jack.

	Here, a stereo system is used
Stereo	for only the Backing sound,
	while the instrument/effect
System	sound goes into one or two
Use this (the L/L + R) jack	guitar amps.
if only one amp is available.

Example 4 — Mixing Console

This set up is best used with the

Amp Simulator effect.

In this system for studio recording applications, the Backing sound

only goes into one channel of a

mixer, while the left and right

Mixing channels of the instrument/effect Console sound go into separate mixer

channels.

This step isn’t necessary for using your GW50 for the first time; however, you may wish later to take advantage of some of the external foot controller and footswitch functions. (See pages 46, 56 for more information.)

6. Make sure that all volume settings are at the minimum: the guitar controls, the INPUT LEVEL and BACKING LEVEL on the GW50 (and the PHONES LEVEL, if you’re using headphones), and the volume on the amp.

20 SETTING UP AND PLAYING YOUR GW50

GUIDED TOUR (TUTORIAL)

Note: To set the controls on the GW50 to minimum, turn them all the way counterclockwise.

7. Turn on the power of all the equipment, starting with the GW50, then the connected amplifier.

*Adjust the LCD SETTING switch on the rear panel to set the LCD for proper viewing. Set it to FLOOR when you are using the GW50 on the floor, and to DESKTOP when you have it set on a table or desk in front of you.

8.Before turning up the volume and trying to play, set all effects to off.

To do this, press [MANUAL] (even if the [MANUAL] LED is lit) …

9. While playing your guitar, slowly bring up the volume controls to suitable levels — starting with the amp, then the guitar output.

Finally, adjust the input level control on the rear panel. Increase the level slowly as you play the guitar while looking at the INPUT PEAK indicator on the panel. The indicator should flash only slightly when you play the guitar at its loudest.

Also, check that the guitar sound doesn’t have distortion at its loudest.

10. Do the same with the BACKING LEVEL.

First turn the backing on by pressing

[START/STOP]…

…then, if any effect block LED is lit, press Pedal Switches 1–5 to turn all effects off (all effect block LEDs should be off).

off

press these

…then turn up the BACKING LEVEL to a suitable volume.

If you’ve followed all these instructions carefully, you should be able to hear both your guitar sound processed by the effects, and the sound of the backing parts.

Note: To stop the backing, press [START/STOP] again.
