IMPORTANT NOTES
Power Supply
• Do not connect this unit to same electrical
outlet that is being used by an electrical
appliance that is controlled by an
inverter or a motor (such as a refrigerator,
washing machine, microwave oven, or air
conditioner). Depending on the way in which
the electrical appliance is used, power supply
noise may cause this unit to malfunction
or may produce audible noise. If it is not
practical to use a separate electrical outlet,
connect a power supply noise lter between
this unit and the electrical outlet.
• The AC adaptor will begin to generate heat
after long hours of consecutive use. This is
normal, and is not a cause for concern.
• To prevent malfunction and equipment
failure, always make sure to turn o the
power on all your equipment before you
make any connections.
• With the factory settings, the GT-100 will
automatically be switched o 10 hours after
you stop playing or operating the unit. If you
don’t want the unit to turn o automatically,
change the “AUTO OFF” setting to “OFF” as
described on p. 42.
* The settings you were editing will be lost
when the unit is turned o. If you want to
keep your settings, you must save your
settings before turning the unit o.
Placement
• Using the unit near power ampliers (or
other equipment containing large power
transformers) may induce hum. To alleviate
the problem, change the orientation of this
unit; or move it farther away from the source
of interference.
• This device may interfere with radio and
television reception. Do not use this device
in the vicinity of such receivers.
• Noise may be produced if wireless
communications devices, such as cell
phones, are operated in the vicinity of this
unit. Such noise could occur when receiving
or initiating a call, or while conversing.
Should you experience such problems, you
should relocate such wireless devices so they
are at a greater distance from this unit, or
switch them o.
• Do not expose the unit to direct sunlight,
place it near devices that radiate heat, leave
it inside an enclosed vehicle, or otherwise
subject it to temperature extremes. Excessive
heat can deform or discolor the unit.
• When moved from one location to another
where the temperature and/or humidity is
very dierent, water droplets (condensation)
may form inside the unit. Damage or
malfunction may result if you attempt to use
the unit in this condition. Therefore, before
using the unit, you must allow it to stand for
several hours, until the condensation has
completely evaporated.
• Depending on the material and temperature
of the surface on which you place the unit, its
rubber feet may discolor or mar the surface.
You can place a piece of felt or cloth
under the rubber feet to prevent this from
happening. If you do so, please make
sure that the unit will not slip or move
accidentally.
• Do not put anything that contains water on
this unit. Also, avoid the use of insecticides,
perfumes, alcohol, nail polish, spray cans,
etc., near the unit. Swiftly wipe away any
liquid that spills on the unit using a dry, soft
cloth.
Maintenance
• For everyday cleaning wipe the unit with a
soft, dry cloth or one that has been slightly
dampened with water. To remove stubborn
dirt, use a cloth impregnated with a mild,
non-abrasive detergent. Afterwards, be sure
to wipe the unit thoroughly with a soft, dry
cloth.
• Never use benzine, thinners, alcohol or
solvents of any kind, to avoid the possibility
of discoloration and/or deformation.
Repairs and Data
• Please be aware that all data contained in
the unit’s memory may be lost when the unit
is sent for repairs. Important data should
always be backed up computer, in another
MIDI device, or written down on paper (when
possible). During repairs, due care is taken
to avoid the loss of data. However, in certain
cases (such as when circuitry related to
memory itself is out of order), we regret that
it may not be possible to restore the data,
and Roland assumes no liability concerning
such loss of data.
Additional Precautions
• Please be aware that the contents of memory
can be irretrievably lost as a result of a
malfunction, or the improper operation of
the unit. To protect yourself against the risk
of loosing important data, we recommend
that you periodically save a backup copy of
important data you have stored in the unit’s
memory on a computer, or in another MIDI
device.
• Unfortunately, it may be impossible to
restore the contents of data that was stored
in the unit’s memory, on a computer, or in
another MIDI device once it has been lost.
Roland Corporation assumes no liability
concerning such loss of data.
• Use a reasonable amount of care when using
the unit’s buttons, sliders, or other controls;
and when using its jacks and connectors.
Rough handling can lead to malfunctions.
• Never strike or apply strong pressure to the
display.
• When disconnecting all cables, grasp the
connector itself—never pull on the cable.
This way you will avoid causing shorts, or
damage to the cable’s internal elements.
• To avoid disturbing others nearby, try to
keep the unit’s volume at reasonable levels.
You may prefer to use headphones, so you
do not need to be concerned about those
around you.
• When you need to transport the unit,
package it in the box (including padding)
that it came in, if possible. Otherwise, you
will need to use equivalent packaging
materials.
• Use only the specied expression pedal
(Roland EV-5, BOSS FV-500L, BOSS FV500H; sold separately). By connecting any
other expression pedals, you risk causing
malfunction and/or damage to the unit.
• Some connection cables contain resistors.
Do not use cables that incorporate resistors
for connecting to this unit. The use of such
cables can cause the sound level to be
extremely low, or impossible to hear. For
information on cable specications, contact
the manufacturer of the cable.
• When you operate the expression pedal,
please be careful not to get your ngers
pinched between the movable part and the
panel. In places where small children are
present, make sure that an adult provides
supervision and guidance.

* Depending on the circumstances of a particular setup, you may experience a discomfort-
ing sensation, or perceive that the surface feels gritty to the touch when you touch this
device, or the metal portions of other objects, such as guitars. This is due to an innitesimal
electrical charge, which is absolutely harmless. However, if you are concerned about
this, connect the ground terminal (see gure) with an external ground. When the unit is
grounded, a slight hum may occur, depending on the particulars of your installation. If you
are unsure of the connection method, contact the nearest Roland Service Center, or an
authorized Roland distributor, as listed on the “Information” page.
Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in re or explosion)
• Telephone-line ground or lightning rod (may be dangerous in the event of lightning)

Phrase Loop Play
Phrase Loop is a recorder function that lets you record up to 38
seconds (when using monaural recording) of audio, and play it
back by operating a pedal. By layering sounds as you continue
real-time recording and playback, you can create a wide variety of
performances.
You can record a phrase loop with eects, or you can add eects
after a loop has been recorded. Adding eects after-the-fact lets
you create special eects with recorded performances.
* Recorded phrases are deleted when Phrase Loop is switched o
or when the power is turned o.

About the Range of a Target’s Change
The value of the parameter selected as the target changes
within the range dened by “Min” and “Max,” as set on the
GT-100.
When using an external footswitch, or other controller that
acts as an on/o switch, “Min” is selected with O (CLOSED),
and “Max” is selected with On (OPEN).
When using an external expression pedal or other controller
that generates a consecutive change in the value, the value
of the setting changes accordingly, within the range set by
the minimum and maximum values. Also, when the target
is of an on/o type, the median value of the received data is
used as the dividing line in determining whether to switch it
on or o.

About the Range of a Controller’s Change
This sets the operational range within which the value of the setting changes when an expression pedal or other controller that changes
the value consecutively is used as the source. If the controller is moved outside the operational range, the value does not change, it stops at
“minimum” or “maximum.”
* When using a footswitch or other on/o switching controller as the source, leave these at “ACT RANGE LO: 0” and “ACT RANGE HI: 127.”
With certain settings, the value may not change.
Virtual expression pedal system (Internal Pedal / Wave Pedal)
By assigning a desired parameter to the virtual expression pedal, you can produce an eect as though you were operating a physical expression pedal
to change the volume or tone quality in real time.
The virtual expression pedal system provides the following two types of functions, and you can use the SOURCE (p. 37) setting for ASSIGN 1–8 to
choose the desired type.
* If you want to use the internal pedal or wave pedal, set the ASSIGN parameter SOURCE MODE to “MOMENT.”
Internal Pedal
If SOURCE is set to “INT PEDAL,” the virtual expression pedal will begin operating when started by the specied
trigger (INT PDL TRIGGER , p. 38), modifying the parameter specied by TARGET (p. 37).
Reference
For more detailed information on the parameters that can be set using Internal Pedal, refer to “INT PDL TRIGGER
(Internal Pedal Trigger)” (p. 41), “INT PDL TIME (Internal Pedal Time)” (p. 38), and “INT PDL CURVE (Internal Pedal
Curve)” (p. 38).
Wave Pedal
If SOURCE is set to “WAVE PEDAL” the virtual expression pedal will cyclically modify the parameter
specied by TARGET (p. 37) in a xed wave form.

If the EXP PEDAL’s FUNC (p. 34) are the same between 2 patches, the operational status is carried over
when patches are switched.
For example, if EXP PEDAL FUNC is set to FOOT VOLUME in both patches, the one before and the
one after the change, the volume corresponding to the position the pedal is in (angle) at the time of
the patch change will be maintained after the patch change. On the other hand, if the patch being
changed to is set to WAH, the volume will be in accordance with the value set within the patch, and
you’ll obtain a wah eect that is in accordance with a value that reects the current position (angle)

Quick GuideOverviewOutputting SoundEectsSaving
With the GT-100, you can use USB to transmit both digital audio
signals between the GT-100 and your computer.
Installing the USB Driver
Just by connecting the GT-100 to your PC/Mac with a USB cable,
audio signal can be transferred bidirectionally via USB.
By using the specialized driver, you can record, play back, and edit
audio with high-quality sound and stable timing (p. 47).
You can download the special GT-100 driver from the Roland local
website.
You must install the dedicated driver before you make USB
connections.
The program and procedures for installing the driver vary according
to the operating environment; carefully read the Readme included
in the downloaded le.
What is a USB Driver?
A USB driver is software that acts as a go-between
in transferring data between computer applications
(such as recording software and sequencer software)
and the USB device when the computer and USB
device are connected using a USB cable.
The USB driver transmits data from the applications
to the USB device, and conversely, passes messages
from the USB device to the applications.
Application Software
USB Driver
Computer
Computer and the GT-100
If you connect the GT-100 to your PC/Mac by a USB cable, you can
transfer MIDI message bidirectionally via USB. Set the GT-100’s “MIDI
IN SELECT” (p. 45) to “USB (Auto).” On your computer, set the MIDI
input/output ports to “GT-100.”
However, MIDI message transfer via GT-100’s MIDI connectors
become inactivated in this situation.

This is a list of the eects built into the GT-100.
* The product names mentioned in this document are registered
trademarks or trademarks of their respective owners. In this
manual, these names are used because it is the most practical
way of describing the sounds that are simulated using COSM
technology.

SEND/RETURN
This is an eect that produces a long sustain by
evening out the volume level of the input signal. You
can switch it to a limiter to suppress only the sound
peaks and prevent distortion.
This eect distorts the sound to create long sustain.
It provides 21 types of distortion and custom
settings. For the types of distortion that can be
selected for OD/DS, refer to “OD/DS Type List.”
COSM technology simulates dierent preamp
characteristics, speaker sizes, and cabinet shapes.
For the amp types that can be selected for the
preamp, refer to “Preamp Type List.”
This adjusts the tone as a equalizer. A parametric
type is adopted for the high-middle and low-middle
range.
With FX1 and FX2, you can select the eect to be
used from the following. You can select the same
eect for FX1 and FX2. For the eects that can be
selected for FX1 and FX2, refer to “FX1/FX2 Eect
List.”
This eect adds delayed sound to the direct sound,
giving more body to the sound or creating special
eects.
In this eect, a slightly detuned sound is added to
the original sound to add depth and breadth.
This eect reduces the noise and hum picked up
by guitar pickups. Since it suppresses the noise in
synchronization with the envelope of the guitar
sound (the way in which the guitar sound decays
over time), it has very little eect on the guitar
sound, and does not harm the natural character of
the sound.
Within the eect chain, the point where the signal
is split into channels “A” and “B” is called the “divider,”
and the point where the two signals are recombined
is called the “mixer.”
You can use the divider to switch between channels
“A” and “B,” to assign strongly picked notes and softly
picked notes to dierent channels, or to assign
dierent frequency bands of your guitar sound to
dierent channels.
The mixer lets you adjust the volume balance of
channels “A” and “B,” place them in the stereo eld, or
slightly delay the sound of channel “B” to produce a
spacious sound.
You can connect an external eects processor
between the SEND jack and RETURN jack, and use it
as one of the GT-100’s eects processors.

SOUND HOLD
You can produce a wah eect with the lter
changing in response to the guitar level.
This changes the ltering over a periodic cycle,
providing an automatic wah eect.
You can control the wah eect in real time by
adjusting the [EXP] pedal or the expression pedal
connected to the SUB CTL 1, 2/SUB EXP jack.
This is an eect that produces a long sustain by
evening out the volume level of the input signal.
You can also use it as a limiter to suppress only the
sound peaks and prevent distortion.
The limiter attenuates loud input levels to prevent
distortion.
This eect distorts the sound to create long
sustain. It provides 21 types of distortion. For the
types of distortion that can be selected for OD/DS,
refer to “OD/DS Type List.”
* “CUSTOM” is not available.
This adjusts the tone as a equalizer. You can adjust
the sound quality in ten bands.
Adjusts the tonal quality. You can adjust the sound
quality in four bands.
Simulation of the characteristics of particular guitar
components such as pickups and dierent guitar
bodies allows you to switch among a number of
dierent guitar types all while using a single guitar.
This produces a volume-swell eect (“violin-like”
sound).
This is a synth sound that processes the guitar
input signal.
This simulates the sound of the sitar.
This adds a note one octave lower, creating a richer
sound.
This eect changes the pitch of the original sound
(up or down) within a range of two octaves.
Harmonist is an eect where the amount of
shifting is adjusted according to an analysis of the
guitar input, allowing you to create harmonics
based on diatonic scales.
You can have sound played on the guitar be held
continuously. This eect allows you to perform the
melody in the upper registers while holding a note
in the lower registers.

produced by the pickup on an acoustic electric
guitar, creating a richer sound similar to that
obtained with a microphone placed close to the
guitar.
By adding varied-phase portions to the direct
sound, the phaser eect gives a whooshing,
swirling character to the sound.
The anging eect gives a twisting, jet-airplanelike character to the sound.
Tremolo is an eect that creates a cyclic change in
volume.
This produces an eect like the sound of a rotary
speaker.
This models a Uni-Vibe.
Although this resembles a phaser eect, it also
provides a unique undulation that you can’t get
with a regular phaser.
With the volume level of the left and right sides
alternately changing, when playing sound in
stereo, you can get an eect that makes the guitar
sound appear to y back and forth between the
speakers.
This consecutively interrupts the sound to create
the impression that a rhythm backing phrase is
being played.
This eect creates vibrato by slightly modulating
the pitch.
This creates a bell-like sound by ring-modulating
the guitar sound with the signal from the internal
oscillator. The sound can be unmusical and lack
distinctive pitches.
Frequency band division is employed to produce
two dierent choruses, one for low frequencies and
one for higher frequencies, for both the left and
right channels (for a total of four). This allows you
to achieve a more natural chorus sound.
This is a delay with the maximum delay time of
1,000 ms. This eect is useful for making the sound
fatter.
When the OUTPUT is set to “MUTE” in the Tuner mode, even the direct
sound will not be output by setting the Tuner to “On” (p. 24).
Move the controller (pedal) to which it is assigned.
Check the settings for the connected device.
Use a connection cable that does not contain a resistor.
Lower these values.
Depending on the software settings, audio signals may end up
looping. You can use the following methods to prevent this from
happening.
• Stop playback with the software, and set Soft Thru to O.
• Switch the software’s audio input o.
• Set USB IN-OUT MODE to something other than “REAMP.”
If PREFERENCE: PREAMP is set to “SYSTEM 1–3,” the preamp settings
won’t change when you switch patches.
If you want to make preamp settings individually for each patch, set
the above setting to “PATCH.”
When the Assign Source is set to “INT PEDAL” or “WAVE PEDAL”, the
eect parameter set as the Assign Target changes automatically.
If you want to be able to change the parameters manually with the
knobs, rst switch o Assign to deactivate the Internal Pedal System.
When “INPUT LEVEL” is set for the Assign Source, the eect parameter
set as the Assign Target changes automatically according to the level of
the input from the guitar (the playing dynamics).
If you want to be able to change the parameters manually with the
knobs and dial, rst switch o Assign.
On the GT-100, patches can be selected only when the Play screen is
displayed. Press [EXIT] to return to the Play screen (p. 21).
To control a parameter using the expression pedal or footswitch, make
sure the eect that contains the parameter you intend to control is
switched on.
If the preference is set to “SYSTEM,” the patch assignment will be
ignored. If you want to enable the settings of the patch, change the
preference for the corresponding parameter to “PATCH”.
Make sure that the controller number of both devices match (p. 44).
Although the unit’s expression pedal has been set for optimal operation at the factory, extended use and certain operating environments
can result in the pedal going out of adjustment. Adjust the expression
pedal (p. 36).
