Introduction
IMPORTANT NOTES
Thank you for purchasing the Roland GP-100 Guitar Preamp/
Processor. in order to take full advantage of the GP-100's function-
ality, and enjoy long years of trouble-free use, please read this
manual carefully.
Main Features
Reproduces Classic Guitar Amps
The GP-100 provides precise reproductions of many of the guitar
amps that have achieved status as classics. It provides not just a
simulation of distortion and speaker response, but a comprehen-
sive emulation that reproduces the unique tonal changes, nu-
ances, andeven the ways in which interference might be produced
as a result of the placement of various pieces of equipment in the
setup — all based on an exhaustive analysis of the electronic parts
and circuits that were actually used in the original guitar amps.
Simple operations allow you to select a desired type of guitar amp,
and you can adjust gain, volume and the various tone controls to
create the perfect sound for your system.
Analog-Feel Controls
Guitar preamp operation features an “analog feei.” The knobs on
the front panel provide immediate and intuitive control.
Speaker Simulator Function
The built-in speaker simulator function not only provides the
choice of stack, built-in, and compact amplifier types, but also lets
you control the mic placement — making it a powerful ally for
direct-line recording.
High-Quality Signal Processor
The GP-100 also includes a professional quality signal processor
designed especially for guitar. It provides compressor, wah, cho-
rus, delay, reverb, and even a pitch shifter with “Harmonist”
(intelligent pitch shifting). With the signal processor and preamp
working together, the GP-100 is all you need to create and perfect
your guitar sound.
FullRange of Connectorsfor Flexibility
Two sets of programmable send/return jacks are provided, and you
can freely specify their location in the signal path. Two pairs of
programmable stereo outputs are also provided.
In addition, the two external control jacks allow external devices
to be turned on/off etc.
Rich Array of Control Functions
A total of 400 settings (200 Preset and 200 User) can be stored as
Patches. Patch settings can be recalled instantly using the front
panel knob or by MIDI program changes.
Control assign settings allow you to have realtime control over a
maximum of 16 parameters. An FC-200 MIDI Foot Controller
(optional) can be connected to control the GP-100 via foot pedal.

How the GP-100 Is Organized
The GP-100 is a preamp/processor that provides comprehensive
control over your guitar sound, The GP-100 is organized as
follows.
<Preamp>
The preamp determines the basic distortion and tone color of the
guitar. With the guitar amp type setting and the settings of the two
volume and four tone controls, you have the tools for some serious
sound-making.
There are two ways in which the preamp can be used. Its settings
can be linked together with the internal effects as part of the settings
of a Patch (“coupled”), or it can be used independently from the
internal effects so it is controlled directly by the settings of the
knobs (“separate”).
<Signal Processor>
The signal processor provides a full array of the high quality digital
effects indispensable for creating your own personal guitar sound.
The connection order and settings for each effect can be stored as
part of a Patch.
Signal processor Patches can contain not only the effect settings,
but also the preamp settings, send/return settings, and external
device control settings.
How to Use This Manual
This manual explains the procedures and functions used for
normal playing, and how to make various settings. Itis divided into
five major sections. Read each section as necessary.

This section explains the basics of the GP-100; how to connect the
GP-100 to external devices, and how to select Patches, etc.
Section 2 Modifying various settings
This section tells how to modify the settings of the preamp and
signal processor. It explains how to make the settings that are
stored in a Patch. Read this section when you wish to create effect
sounds, or to modify the settings of various functions.
Section 3 Effect Guide
This section explains how the algorithms are organized, and the
functions of the effects and various parameters.
Section 4 Using MIDI

Modifying various settings
The GP-100 stores 400 Patches, each of which.contains a connec-
tion order and settings for the built-in effects and settings for the
preamp, etc. This section will explain how to edit the contents of
a Patch to create a new effect sound Patch, and how to store your
new settings.
Before You Begin Creating
Sounds
Before you begin creating sounds there are several things that you
need to understand.
About the Preamp
The GP-100 contains a preamp function. This consists of a guitar
amp type selection, and the settings of the two volumes and four
tone controls. The preamp section creates the basic distortion and
tonal characteristics of the guitar sound.
There are two ways in which the preamp can be used. Its settings
can be linked together with the internal effects as part of the settings
of a Patch (“coupled”), or it can be used independently from the
internal effects so it is controlled directly by the settings of the
knobs ("separate").
User Area and Preset Area
The 400 Patches in the GP-100 are divided into the User area and
the Preset area.
User area (Patch numbers 1—200)
Patch numbers in the User area can be used to store effect sounds
that you create.
Preset area (Patch numbers 201—400)
Patch numbers in the Preset area cannot store effect sounds that
you create. However, you can start with a Preset area Patch, and
modify and store it in the User area.
About Algorithms
The “algorithm” determines the types of effects that will be
available and how the effect parameters will be organized. Each
ofthe five algorithms inthe GP-100 has been created with atypical
performance situation in mind, so you can conveniently get the
sound you are looking for. You are also free to modify the settings
of each effect in the algorithm.
What a Patch Contains
Each Patch number inthe user area contains the following settings.
Preamp settings
The algorithm that is used
The order of the effects
The settings for each effect
Output level settings
OUTPUT Channel settings
External control settings
Make these settings when you wish to control an external
device (e.g., selecting amp channels) from the GP-100.
Control assign (16 types)
Make these settings when you wish to control GP-100
parameters from an external pedal or MIDI device con-
nected to the GP-100.
The effect name
е Editing Procedure
Select a Patch that is close to the effect sound you want to
create. Then check the Algorithm Type used by that Patch and
refer to “Section 3. Effect guide” (p. 30) to see how the effect
sound is organized.
2 Copy the selected Patch to a Patch number (User area) whose
previous data you do not need to keep.
* If you are only modifying the Patch that you selected in step 1 (and
not creating a new Patch), there is no need to copy it.
3 Modify the contents of the Patch.
The effects included in the algorithm each have several
parameters. Modify the value of each parameter to create the
new effect sound you want.
4 Assign a name to the new effect sound.
5 Storing the new effect sound.
The modified settings of the new effect sound are temporary,
and will be lost if you turn the unit off or select another Patch.
If you want to save your new effect sound, use "the Write
operation" (p. 24) to store it.

Effect Sound Settings
Although each algorithm is unique because it uses a particular
selection of effects which are configured in a certain way, the basic
procedure for creating sounds is the same. Here we will explainthe
procedure for making effect parameter settings. For an explanation
of each parameter, refer to “Section 3 Effect Guide” (p. 30).
How the parameters are organized
The GP-100 lets you access all parameters of the algorithm using
only the PARAMETER knob. As you rotate the PARAMETER knob
to the right, the parameters will appear in the following order.
Effect on/off and effect connection order
Parameters for each effect
Realtime control of parameters
Effect name
The Skip function
(When selecting a parameter)
When calling up a parameter in the display, you can jump to the
first parameter of each effect by pressing the PARAMETER knob as
you rotate it.
(When modifying a value)
When modifying a value, you can more rapidly make the value
change by pressing the VALUE knob as you rotate it.
Effect On/Off Settings
Each algorithm combines the use of a multiple number of effects.
you can turn on whichever effects you wish to use, while effects
you do not wish to use can be turned off. Effects that have been
turned on are indicated by a e, displayed at the right of the effect
name.
* The effect names are displayed in abbreviated form. To see the effect
names in full, refer to "Section 3 Effect Guide" (p. 30).
