Congratulations and thank you for purchasing the Yamaha GW10
Guitar Performance Effector. The GW10 is a portable and conven­ient multi-effect device for guitar (as well as other instruments).
The high-quality effect sound and the flexible pedal control over
certain parameters make the GW10 ideal for signal processing in
home recording, studio, and live performance applications.

Some of the advanced features of the GW10 include:

• Three basic effect blocks, featuring Distortion, Chorus and Delay.

• Additional effect types within each block, such as Compressor,
Overdrive, Crunch, Wah, Amp Simulator, Equalizer and Pitch Shifter
— plus a built-in Noise Gate.

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

• Convenient parameter control over all effects, yet exceptional ease­of-use — you can adjust the parameters of the effect blocks much as
you would on conventional pedal effects.

• Built-in Foot Controller, which not only allows for easy volume
adjustment, but gives you realtime control over one of various effect
parameters. It also features a switch (past the maximum point) for
instantly turning selected effects on and off.

• User memory for storing up to 20 effect programs, selectable with
the Pedal Switch.

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

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

You are probably eager to try out your new GW10 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 PRECAUTION S
section (page 2). This tells you briefly how to care for your new GW10, how to
avoid damaging it, and how to ensure long-term, reliable operation.

Next, read the SYSTEM OV ERVIEW (page 8). This provides an important
introduction to the internal organization of the GW10, enabling you to better
understand its various functions and use the device to its full potential.

To actually start using the GW10, read the GUIDED TOUR (page 12). It
guides you step-by-step in setting up your GW10, 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.

The REFERENCE section (page 24), 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 CON TROLS AN D TERM IN ALS (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 APPEN DICES section (page 50) is also very helpful. It lists
page numbers for virtually every function, feature, control and terminal found on
the GW10, and lets you find the information you need quickly and easily.

Other parts of the APPENDICES section provide additional useful information:
lists of the effect programs of the GW10, tips on troubleshooting (when some­thing doesn’t work as expected), and other important information.

PRECAUTIONS

■ USE THE CORRECT POWER SUPPLY

Power to the GW10 should be supplied only from the appropriate Yamaha
AC adaptor (the PA-3 or another adaptor specifically recommended by
Yamaha). 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 GW10. (The correct
input voltage is marked on the adaptor.)

■ MEMORY BACKUP

The GW10 contains a special long-life lithium battery that retains the
contents of the internal RAM memory even when the power is turned off.
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, the MEMORY/TUNER Indicator lights “L” then “o”
three times when the power is turned on.

When this happens, write down all necessary settings to a piece of paper
(or on copies of the chart provided on page 48), then have the battery
replaced by qualified Yamaha service personnel as soon as possible. DO
NOT ATTEMPT TO REPLACE THE BACKUP BATTERY YOURSELF!
(Keeping records of your original settings is necessary since the memory
contents cannot be preserved when the battery is changed.)

■ AVOID EXCESSIVE HEAT, HUMIDITY, DUST AND VIBRA-

TION

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 GW10 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 GW10 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 MAKING OR REMOV-

ING 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.

2

■ 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 only with water — making sure
to wipe the case off again with a dry cloth.

■ FOOT CONTROLLER

Do not put your fingers underneath or inside the Foot Controller pedal,
since some of the parts there have a lubricant or grease applied to them.
Doing so may not only get your hands dirty, but also remove some of the
grease necessary for smooth pedal operation.

■ ELECTRICAL INTERFERENCE

Since the GW10 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 GW10 further away from the affected equip­ment.

PANEL CONTROLS AND TERMINALS

This section shows and explains all of the controls and terminals of the GW10.
Since the explanations 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 GW10, when you need specific
information on a certain control or terminal.

■ The Effect Structure of the GW10

Keep in mind as you use the GW10 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 is made up of three effect blocks and a Foot Controller
block, 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 (except
Noise Gate) is made up of three 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.

SETTING UP AND PLAYING YOUR GW10

Once you’ve taken your GW10 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.

1

First, make sure that the power switch on the GW10 is off before making
ANY connections.

2

Plug the DC output cable from the power adaptor into the DC IN terminal
on the rear panel, then plug the adaptor into a convenient AC outlet.

THE EFFECTS OF THE GW10

The GW10 is equipped with a comprehensive set of effects designed specifically
for the guitar player. You can switch these effects on and off as needed and
adjust them quickly and easily from the panel controls.

There are three groups or “blocks” of effects — Distortion, Chorus and Delay —
plus a special Foot Controller block that includes a Noise Gate effect and the
Foot Controller settings. The Distortion block includes Crunch, Overdrive and
Compressor effects, while the Chorus block also features Pitch Shift, Wah,
Equalizer, and Amp Simulator effects.

(Refer to the EFFECTS AND PARAMETERS section, page 27, for more
detailed descriptions and explanations of these effects.)

With these three effect blocks, used individually or simultaneously, the GW10
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.

PLAYING WITH THE PRESET EFFECTS

Now that you’ve set up your GW10 and are ready to use it, let’s try playing
with some of the preset effects. (If you haven’t already done so, read through
the SYSTEM OVERVIEW section on pages 8–11 for information on the basic
structure of the GW10 and how to select effect programs.)

1

First, try playing with a bright chorus effect. Use the M Pedal
Switch to select bank 3, program number 5. (Hold down the Pedal Switch
to select the desired bank, and press it repeatedly to advance to the proper
program number; see pages 10–11.)

USING THE FOOT CONTROLLER

TO CHANGE THE SOUND

The Foot Controller is one of the most convenient and flexible features of the
GW10. It not only allows you to control volume, but also lets you continuously
change certain effect parameters as you play. The examples below should give
you a taste of what the Foot Controller functions can do for your sound.

1

Let’s use one of the volume functions of the Foot Controller first. Select
bank 4, program number 3.

2

Bring the Foot Controller to the maximum position and play your guitar.
This is the maximum volume and is ideal for playing a solo.

3

Now, stop playing and bring the pedal all the way to the minimum posi­tion, then start playing again.

Notice how the volume of the sound changes to a level suitable for backing
parts. As you can see, the Foot Controller is an easy and instant way to
change from one volume setting to another.

4

Next, let’s use the Foot Controller to change the sound in realtime. Select
bank 1, program number 2.

As you play your guitar, slowly rock the pedal back and forth. Listen to the
“wah-wah” effect in the sound as you move the Foot Controller.

5

Finally, select bank 3, program number 2.

In this example, set the Foot Controller first to the minimum position and play
your guitar. As you continue playing, slowly bring the pedal to the maximum
position. Notice how a rich, natural chorus effect gradually blends in with the
sound as you press the pedal toward the maximum.

As you can see, the Foot Controller is an extremely versatile and powerful
performance tool, giving you broad control over the sound as you play, without
forcing you to take your hands from your instrument.

Look again through the Preset Effect Program list on page 44, noting which
programs take advantage of the Foot Controller functions, and try playing with a
few of them to hear how they sound.

TURNING SPECIFIC EFFECTS ON AND OFF

Since the sound of an effect preset is actually made up of three different effects,
you can make distinct changes in the sound by turning individual effect blocks
on and off.

Using the Foot Controller to Turn Effect Blocks On and Off

The Foot Controller can be used to instantly turn
pre-assigned effect blocks on and off. The green
ON OFF GROUP LEDs above the Effect Block
buttons indicate which effect blocks are assigned
for this. For example, if the green LEDs above
H and L are lit, the Chorus and Delay

DISTORTION BLOCK

OD / DST
COMP

SENSE

The Distortion block features the following
effects: Overdrive, Crunch, Distortion, and
Compressor.

Overdrive/Distortion (OD/DST)

Drive

Determines the intensity of the Overdrive,
Crunch or Distortion sound. The higher the
value, the greater the distortion.

HINT ■

For best results, set the Drive parameter

roughly between the 12:00 and 3:00 positions.

Type

Determines the type of distortion effect: Over­drive, Crunch, or Distortion. Overdrive recreates
the warm, natural sound of a tube amp being
overdriven. Crunch is a rich distortion effect
ideal for power chords and Rock’n’Roll. Distor­tion is a hard, more metallic distortion sound,
and is excellent for screaming lead lines.

The positions from minimum to roughly 10:00
correspond to Overdrive, from about 11:00 to
1:00 corresponds to Crunch, and from about 2:00
to maximum corresponds to Distortion. Within
each effect is also three separate settings: Low,
Mid, and High.

to avoid sudden jumps or drops in level when

■

Compressor (COMP)

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. Normally, 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.

Sense

Determines the threshold level of compression.
Compression is applied to signal levels above the
Sense point, while signals below this point are
unaffected. The minimum setting virtually
allows the entire signal to pass without being
compressed (minimum compression), while the
maximum setting applies compression to the
entire signal (maximum compression).

Attack

Determines the amount of time it takes for
compression to begin after an input signal is
detected. Longer attack times (when dial is
turned toward maximum) let through more of the
natural attack of the input signal.

Output

Determines the level of the Compressor sound.
Settings past the 12:00 position are used for
boosting the overall signal to an appropriate
level, since compression effectively lowers the
level of the sound.

amount of pitch shift independently for the left and
right channels, creating three separate pitches (includ­ing the original direct signal). One application for
this would be to create a natural, spacious stereo
chorus effect in which the left and right pitches are
detuned slightly relative to the direct sound. Other
applications 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 harmonies
and fill out the sound.

Pitch Left (PITCH L)

Determines the amount of pitch shift for the left
channel, up to one octave above or below the
input pitch. The 12:00 position on the dial
corresponds to unison pitch, while the pitch can
be continuously detuned between the 9:00 and
3:00 positions. Fixed pitch shifts are available
past those positions: an octave down at 7:00, a
5th down at 8:00, a 4th down at around 9:00, a
4th up at around 3:00, a 5th up at 4:00, and an
octave up at 5:00.

Unison pitch

Feedback

Determines the amount of Chorus signal that fed
back again to the Chorus input. Higher values
result in a stronger, flanger-like sound.

Depth

Determines the depth of the pitch modulation, or
how widely the pitch is varied.

Pitch Shift

Pitch Shift lets you change the pitch of the sound, up
to an octave above or below the pitch of the input
signal. Since the effect is stereo, you can set the

Pitch Right (PITCH R)

Determines the amount of pitch shift for the

Pitch Left above.)

Mix

Determines the level of the Pitch Shift sound.
The minimum setting corresponds to 0%, or no

Pitch Shift output (only the original sound is
heard). The midpoint setting corresponds to
50%, or an equal mix of the original direct
sound and the Pitch Shift output. The maximum
setting corresponds to 100%, or no original

Wah

Wah is a filter sweep effect that, as its name
implies, produces a “wah” type sound. Two
different Wah types 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 the Foot Controller. The Touch
type is normally active; to select Pedal, make
sure WAH is enabled in the Foot Controller
block. The illustration below shows how the
various parameters and two types are related.

RANGE

HINT — About the Wah Types (Touch and
Pedal) ■

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. Touch is normally active when you
select the Wah effect.

The Pedal setting lets you sweep the filter
manually with the Foot Controller. This setting is
available only when WAH has been selected in
the Foot Controller block. If the WAH LED in the
Foot Controller block is already lit, the Pedal type
is active.

To change between the two types, press
until one of the Foot Controller block LEDs
flashes, then press
(for Pedal type) or another parameter’s LED (for
Touch type).

The Touch type lets you control the

Sense

Determines how sensitive the Wah effect is to
the instrument input. (Not available for Pedal
Wah operation.) The higher the value, the more
sensitive the trigger of the Wah effect becomes
to low level signals; the movement of the band
pass filter responds to even slight level changes.

Pedal, the movement of the Foot Controller determines the
movement of the isolated frequency across the set range.

Touch, the level of the guitar signal determines the position
of the isolated frequency within the set Range. When the
level of the guitar is low, the isolated frequency remains
around the minimum frequency of the set Range. As the
guitar level increases, the isolated frequency moves further
toward the maximum.

The Wah effect employs a movable band pass filter to create
the filter sweep or filter emphasis effect. Frequencies on
either side of the center frequency (set in the Frequency
parameter) are cut or filtered out, isolating the center
frequency. This frequency band is then moved across the
specified frequency range (set in Range), as shown in the
Pedal and Touch portions of the graph above.

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 (FREQ)

Determines the center frequency of the band pass
filter. The Wah effect sweeps this isolated
portion below and above the center frequency,
over a specific frequency range determined by
the Range parameter. (See illustration at left.)

Range

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. (See illustration at
left.)

Equalizer (EQ)

The Equalizer effect provides fine tone control
over the sound with a three-band equalizer.

Low

Determines the amount of boost or cut applied to
the low frequencies. The 12:00 position corre­sponds to flat response or no equalization.

Combo

TubeStack

A definite change in the sound can be heard
when crossing the “line” between two separate
types.

Mid

Determines the amount of boost or cut applied to
the midrange frequencies. The 12:00 position
corresponds to flat response or no equalization.

High

Determines the amount of boost or cut applied to
the high frequencies. The 12:00 position corre­sponds to flat response or no equalization.

Take care when using maximum levels;

HINT ■

distortion could result, especially when all
parameters are set to the maximum.

■

Amp Simulator (AMP)

This effect realistically reproduces the character­istic sound of a guitar amplifier, and provides a
natural sound for direct recording purposes when
not using an external amplifier. When using an
amplifier, it also provides a convenient way to
change the sound characteristics of that ampli­fier. Amp Simulator is particularly effective
when used with one of the Distortion effects.

Tone

Determines the degree to which high frequencies
are cut or boosted. Turning the parameter dial
counterclockwise decreases the high frequencies,
while turning it clockwise boosts them.

Mix

Determines the level of the Amp Simulator
effect. The minimum setting corresponds to 0%,
or no Amp Simulator output (only the original
signal is heard). The midpoint setting corre­sponds to 50%, or an equal mix of the original
direct signal and the Amp Simulator output. The
maximum setting corresponds to 100%, or no
original signal output (only the Amp Simulator
effect is heard).

HINT ■

For direct recording purposes, a setting of
100% is recommended.

■

Type

Determines the type of amplifier that is simu­lated: Stack, Combo, or Tube. Stack recreates
the powerful sound of a huge amp/speaker setup,
Combo recreates a compact amp cabinet, and
Tube recreates the warm sound of a tube ampli­fier.

The positions from minimum to roughly 10:00
correspond to Stack, from about 11:00 to 1:00
corresponds to Combo, and from about 2:00 to
maximum corresponds to Tube.

DELAY BLOCK

DLY

DELAY

TIME

FEEDBACK MIX

Delay

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 — especially since this is
a stereo delay effect. Generally, it is an effec­tive way to bring the sound to life and make it
sound more natural. Delay can also be used for
special applications, such as creating rhythmic
repeats in the sound.

The Delay effect of the GW10 also has a special
Doubling feature, which adds two slightly delayed
repeats to the original signal, and outputs them
separately in the left and right outputs (as shown in
the Delay Parameters illustration at right). The
Doubling sound is too fast to be heard as a distinct
delay, but instead adds depth and fullness to the
direct sound, giving the impression of more than
one instrument being played.

Delay has been placed last in the effect chain of
the GW10, since it is most often used to repro­duce the echoes and ambience that follow a
sound when heard in an actual performance
environment.

Time — Range: 5 - 660 ms

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 reverb­type effect. Longer times are used for special
effects, like creating long echoes or steady
rhythmic pulses.

Feedback

Determines the number of the delayed repeats
and the level of the doubling sound. As shown
in the illustration above, settings between 7:00
and 8:00 result in only the direct and Doubling
sounds being heard. Settings between 8:00 and

9:00 add a single delayed repeat without Dou­bling. Settings between 9:00 and 12:00 repeat
the delay and Doubling a few times, while for
higher values the repeats carry 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

Determines the level of the Delay sound. The
minimum setting corresponds to 0%, or no Delay
output (only the original signal is heard). The
maximum setting corresponds to 50%, or an
equal mix of the original direct signal and the
Delay output.

NOISE GATE

Noise Gate is a separate effect that is placed
between the Distortion block and the other two
blocks, 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.
Noise Gate is active only when the Distortion
block is also active and one of the distortion­type effects has been selected (Overdrive,
Crunch, or Distortion); when Compressor is
selected, the Noise Gate is off.

To adjust the Noise Gate parameters, select the
Foot Controller block with the B button,
then use the two parameter dials below NOISE
GATE.

Threshold

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
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.

Release

Determines the time of the decay, from when the
input signal crosses the Threshold point. (Since
this control introduces subtle changes to the
sound, some experimentation may be necessary;
also see Hint below.)

Achieving the best results with the Noise

HINT ■

Gate may take some experimentation. When
Release is set too close to the minimum and the
Threshold setting is not low enough, the noise
may come back in soon after the sound dies out,
creating an unnatural sounding decay. When
Release is set too close to the maximum, the
noise may remain too long and sound as if it is
gradually increasing in volume. For optimum
results, avoid the extreme settings (especially in
Release) and use low-to-median values.

FOOT CONTROLLER OPERATIONS

The Foot Controller of the GW10 can be used as a volume pedal or as a realtime
controller for specific effect parameters. Moreover, when used as a volume
pedal, it can be placed in one of three positions in the effect chain, and be given
a minimum volume setting other than zero (for when you need to easily change
between two different volume settings).

The Foot Controller also features a switch (just beyond the maximum setting)
for turning selected effect blocks on and off.

Volume Pedal Control —

Volume Position and Minimum Volume

The Volume Position feature lets you specify the
point in the effect chain at which the volume
pedal control is placed.

Minimum Volume can be set to a level some­where between 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.

OPERATION

If q D is selected, the Distortion sound can be
controlled with the Foot Controller.

If w H is selected, the Foot Controller can be used
to control the Distortion and Chorus sound, even to the
point of taking out Distortion and Chorus at the
minimum position but leaving the Delay sound.

If e L is selected, the entire sound level is
controlled with the Foot Controller.

When Wah is selected in the Chorus block and the

and e L — following the output of the
Delay block or at the end of the effect chain.

Parameter Control

The Foot Controller can be used to continuously
change an effect parameter in realtime, as you
play. One of nine different parameters can be
selected: Wah Filter Sweep, Distortion Drive,
Compressor Sense, Chorus Depth, Pitch Shift
Mix Balance, Wah Range, Equalizer High Gain,
Amp Simulator Mix Balance, or Delay Mix.

3

Play the connected instrument and try using
the Foot Controller to control the selected
parameter. (When the Foot Controller is
enabled for parameter control, the corre­sponding parameter knob is disabled.) The
Foot Controller changes the value of the
selected parameter over its entire range.

OPERATION

To select the parameter for Foot Controller
control, press B repeatedly until the
Foot Controller block is selected. (One of
the LEDs in the Foot Controller block will

Effect Block On/Off Control

The Foot Controller can also be used to instantly
turn a selected effect block (or blocks) on and
off. The green ON OFF GROUP LEDs above
the Effect Block buttons indicate which block or
blocks have been enabled for this function.

To select the effect blocks for on/off switching
with the Foot Controller, press and hold down
the appropriate Effect Block button(s) for about
one second, until the green ON OFF GROUP
LED above the button lights. Any or all effect

blocks can be selected.
To turn the selected effects on or off, push the
Foot Controller down to its maximum setting,
then firmly press it once.

■ DISABLING THE EFFECT ON/OFF SWITCHING OF THE FOOT

CONTROLLER

The GW10 features a “hidden” switch for
disabling effect block on/off control with the

Large screw

Foot Controller. Doing this also gives you
increased range in the Foot Controller opera­tion. Normally, the Foot Controller range stops
not at the absolute maximum, but at the point
where spring pressure starts. By disabling on/

Screw cap

off control, the Foot Controller range can be
extended to cover up to the absolute maximum.

NOTE ■

also disables Tuner on/off control with the Foot
Controller. However, an alternate method for
turning on the Tuner function is available; see
the Hint on page 41.

Disabling the effect on/off control here

TROUBLESHOOTING

Even though the GW10 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 GW10.

POSSIBLE CAUSE AND SOLUTIONPROBLEM

The instrument (guitar)
sound cannot be heard.

The effect sound cannot
be heard or is nearly
inaudible.

The sound is too loud or
the effect sound is abnor­mal or unexpected.

• Check that all connections have been properly made and that all
levels have been appropriately set (including the INPUT LEVEL
control on the rear panel and the Foot Controller).

• Check that the Output parameter of the Distortion block is set to an
appropriate level.

• Make sure that the Tuner is not active. (See Tuner operation step
#5, page 41.)

• Check all of the above points (for when the instrument sound
cannot be heard).

• Check that the desired effect blocks are turned on (LEDs are lit).

• Check that the Mix, Depth and Range parameters of the Chorus and
Delay blocks are set to appropriate levels.

• The guitar level is too loud (the INPUT PEAK LED is lit continu­ously). Set the input level of the GW10 and the output level of the
guitar appropriately. (See pages 13, 14).

• In general, remember that the parameters within an effect interact
with and depend on each other. If you are using more than one
effect, try each effect block separately, checking and adjusting all
parameters in the effect until you get the sound you want.

• If there is too much distortion or noise, check:

• That the Drive and Output parameters of the Distortion block
are set to appropriate levels.

• That the Equalizer gain controls (Low, Mid and High) have not
been set too high.

• That the Mix parameters of the Chorus and Delay blocks are set
to appropriate levels.

• That the Noise Gate settings are appropriate.

• Also check your connected amplifier. If you are getting too much
distortion, check that the GW10 is connected to the clean channel
and not to the distortion channel.

42

Appendices

The effect sound doesn’t
change, even when the
parameter dials are
adjusted.

POSSIBLE CAUSE AND SOLUTIONPROBLEM

• Make sure that the effect in question is enabled.

• This may happen when the Foot Controller is used for parameter
control; the controlled parameter’s parameter knob is disabled.

The Foot Controller
doesn’t have any effect
on the sound.

The Write, Copy or Swap
operations cannot be
selected.

• If you are using the Foot Controller to control volume, make sure
that the Minimum Volume has not been set to the maximum. If it
has been, moving the Foot Controller will not change the volume of
the sound. (See page 33.)

• If you are using the Foot Controller to change an effect’s parameter
(such as Wah or Chorus Depth), make sure that the effect block of
the parameter to be controlled has been turned on; otherwise the
Foot Controller functions only as a volume pedal. (See third note
on page 34.)

• Make sure that you first hold down the B(NO) button, then
press the T(YES) button.
