LEVEL -20–+20 dB VTG RACK U This models a UREI 1178. Adjusts the overall volume level of the equalizer.
EFFECT GUITAR SIM DEFRETTER Simulation of the characteristics of particular guitar components such as pickups and different guitar bodies allows you to switch among a number of different guitar types all while using a single guitar. Parameter Value Explanation Selects the type of the guitar simulator. SgH Changes from a single-coil pickup tone to a humbucking pickup tone. HgS Changes from a humbucking pickup tone to a single-coil pickup tone.
EFFECT SITAR SIM. PITCH SHIFTER This simulates the sound of the sitar. Parameter SENS DEPTH Value Explanation 0–100 Adjusts the sensitivity of the sitar. When it is set to a lower value, no effect of the sitar is obtained with weaker picking, while stronger picking produces the effect. When it is set to a higher value, the effect of the sitar can be obtained whether the picking is weak or strong. This effect changes the pitch of the original sound (up or down) within a range of two octaves.
EFFECT HARMONIST Parameter Harmonist is an effect where the amount of shifting is adjusted according to an analysis of the guitar input, allowing you to create harmony based on diatonic scales. * Because of the need to analyze the pitch, chords (two or more sounds played simultaneously) cannot be played. * When you are to play the next string while a certain sound is still playing, mute the previous sound and then play the next one with a clear attack.
EFFECT AC. PROCESSOR Parameter Value This sets the cycle of the step function that changes the rate and depth. When it is set to a higher value, the change will be finer. Set this to “Off” when not using the Step function. This processor allows you to change the sound 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. Parameter Value Explanation Selects the modeling type.
EFFECT TREMOLO UNI-V Tremolo is an effect that creates a cyclic change in volume. Parameter Value Explanation WAVE SHAPE 0–100 Adjusts changes in volume level. A higher value will steepen wave’s shape. RATE 0–100, BPM – This models a Uni-Vibe. Although this resembles a phaser effect, it also provides a unique undulation that you can’t get with a regular phaser. Parameter Value Explanation Adjusts the frequency (speed) of the change. Adjusts the rate of the UNI-V effect.
EFFECT SLICER RING MOD. This consecutively interrupts the sound to create the impression that a rhythm backing phrase is being played. Parameter Value Explanation PATTERN P1–P20 Select the slice pattern that will be used to cut the sound. 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.
EFFECT 2X2 CHORUS SUB DELAY Frequency band division is employed to produce two different 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. Parameter Value LOW RATE 0–100 0–100, BPM – * When set to BPM, the value of each parameter will be set according to the value of the “MASTER BPM” specified for each patch.
EFFECT COMMON DELAY This effect adds delayed sound to the direct sound, giving more body to the sound or creating special effects. Parameter Value Explanation DELAY ON/OFF OFF, ON Turns this effect on/off. Parameter 1 ms–2000 ms, BPM – * If you switch patches with the Type set to either DUAL-S, DUAL-P, or DUAL- L/R and then begin to play immediately after the patches change, you may be unable to attain the intended effect in the first portion of what you perform.
EFFECT MODULATE REVERB This effect adds reverberation to the sound. Parameter Value Explanation MOD RATE 0–100 Adjusts the modulation rate of the delay sound. Parameter Value Explanation 0–100 Adjusts the modulation depth of the delay sound. REVERB ON/ OFF OFF, ON Turns this effect on/off. MOD DEPTH This selects the reverb type. Various different simulations of space are offered. CHORUS In this effect, a slightly detuned sound is added to the original sound to add depth and breadth.
EFFECT PEDAL FX FOOT VOLUME PEDAL BEND FOOT VOLUME This lets you use the pedal to get a pitch bend effect. This is a volume control effect. * Because of the need to analyze the pitch, chords (two or more sounds played simultaneously) cannot be played. Normally, this is controlled with the EXP Pedal or the [EXP] pedal connected to the SUB CTL 1, 2/SUB EXP jack.
EFFECT DIVIDER MIXER Within the effect 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 different channels, or to assign different frequency bands of your guitar sound to different channels.
EFFECT SEND/RETURN NS1/NS2 You can connect an external effects processor between the SEND jack and RETURN jack, and use it as one of the GT-100’s effects processors. This effect 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 effect on the guitar sound, and does not harm the natural character of the sound.
EFFECT ACCEL FX TWIST This allows for the use of six different types of Accel effects, which modify the sound over time when you depress the [ACCEL/CTL] pedal. Parameter Value Explanation S-BEND Applies intense bending. LASER BEAM Produces a laser beam-like sound. RING MOD. Produces a metallic sound, creating the impression that the sound is being focused. TWIST Produces an aggressive sense of rotation. Using this in conjunction with distortion will produce an even wilder sense of rotation.
EFFECT MASTER SETTING AMP CONTROL These settings are applied to the overall patch. MASTER SETTING Parameter Value Explanation PATCH LEVEL 0–200 Adjusts the volume of the patch. By connecting your guitar amp’s channel switching jack to the GT-100’s AMP CONTROL jack, you can then use Amp Control to switch the amp channel. Adjusts the BPM value for each patch. * BPM (beats per minute) indicates the number of quarter note beats that occur each minute.
SYSTEM OUTPUT SELECT TOTAL Specify the device (amp) that’s connected to the OUTPUT jacks. Parameter Value Explanation JC-120 Choose this setting if the GT-100 is connected to the guitar input of a Roland JC-120 guitar amp. SMALL AMP Choose this setting if the GT-100 is connected to a small guitar amp. COMBO AMP NS THRESH Value Explanation -20–+20 dB Control the threshold level of the noise suppressor used by each patch. This does not affect the settings of each patch.
SYSTEM Parameter Value Explanation OFF The operational status of the EXP PEDAL’s FUNC (p. 31) is not carried over when patches are switched. If the EXP PEDAL’s FUNC (p. 31) are the same between 2 patches, the operational status is carried over when patches are switched. Display of parameters you can set with KNOB SETTING The parameter names displayed in the Play screen are abbreviated. For details about the parameter names, refer to the chart shown below.
SYSTEM PREFERENCE USB Here you can specify whether settings for the type of connected amp and preamp, control pedal, expression pedal, etc. will be independent for each patch, or whether the same settings will be shared by all patches. Parameter Value OUTPUT SELECT ACCEL/CTL If this is set to PATCH, different settings can be made independently for each patch. If this PATCH, SYSTEM 1–3 is set to SYSTEM, the same settings will be shared by all patches.
SYSTEM Parameter MIX LEVEL Value Adjusts the input level from the computer to the GT-100’s effects . Value * When you have an external MIDI device connected, the MASTER BPM is then synchronized to the external MIDI device’s tempo, thus disabling the MASTER BPM setting. To enable setting of the MASTER BPM, set to “INTERNAL.” SYNC CLOCK * When synchronizing performances to the MIDI Clock signal from an external MIDI device, timing problems in the performance may occur due to errors in the MIDI Clock.
SYSTEM Parameter SUB CTL 1 OUT SUB CTL 2 OUT SUB EXP OUT Value Explanation This sets the controller number when operation data from the footswitch connected to the SUB CTL 1, 2/SUB EXP jack is output as Control Change messages. OFF Control Change messages are not output. This sets the controller number when SUB CTL CC#1–CC#31, 1 pedal operation data is output as Control CC#64–CC#95 Change messages. OFF Control Change messages are not output.
CTL/EXP ACCEL/CTL, EXP SW, SUB CTL 1, SUB CTL 2 Here’s how to assign the parameters that will be controlled by the ACCEL/ CTL, EXP SW, SUB CTL 1 and SUB CTL 2 pedals. Parameter Value Explanation OFF No assignment. ACCEL Switches the ACCEL effect on and off. P.LOOP ON/OFF Switches the PHRASE LOOP on and off. P.LOOP REC/PLY Records/plays back the phrase. P.LOOP STP/PLY Stops/plays back the phrase. P.LOOP CLEAR Clears the phrase DIV CH SELECT Switches between Preamp channel A and B.
CTL/EXP ASSIGN COMMON Parameter Value Explanation INPUT SENS 0–100 This adjusts the input sensitivity when INPUT LEVEL is selected for SOURCE. Parameter Value Explanation SAW WAVEFORM *1 TRI SINE ASSIGN 1–8 PATCH CHANGE This is activated when a patch is selected. * If you want to light the ACCEL/CTL pedal’s LED indicator while the ASSIGN 1–8 function is assigned to the ACCEL/CTL pedal, set the ACCEL/ CTL pedal FUNC (p. 31) to “LED ON/OFF.

CTL/EXP By assigning a desired parameter to the virtual expression pedal, you can produce an effect 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 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.
CTL/EXP 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.
