Appendices

This is a list of the effects 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.

This is an effect 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 effect 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 different 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 effect to be 

used from the following. You can select the same 

effect for FX1 and FX2. For the effects that can be 

selected for FX1 and FX2, refer to “FX1/FX2 Effect 

List.”

This effect adds delayed sound to the direct sound, 

giving more body to the sound or creating special 

effects.

In this effect, a slightly detuned sound is added to 

the original sound to add depth and breadth.

This effect adds reverberation to the sound.

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.

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.
The mixer lets you adjust the volume balance of 

channels “A” and “B,” place them in the stereo field, or 

slightly delay the sound of channel “B” to produce a 

spacious sound.

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.

PEDAL FX is an effect used to control WAH or PEDAL 

BEND with the [EXP] pedal. The SUB EXP pedal 

cannot be used for this control.
FOOT VOLUME is a volume control effect.
Normally, this is controlled with the EXP Pedal or 

the [EXP] pedal connected to the SUB CTL 1, 2/SUB 

EXP jack.

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.

Here you can make USB-related settings for when 

the GT-100 is connected to a computer via USB.

These settings are applied to the overall patch.
