Boss GT-100 Effects Processor

Beyond Vintage

With its next-generation COSM processor, the GT-100 ushers in a new era of expression and sonic capabilities. Recreating the meticulous details of vintage amps and how they behave, the GT-100 excels in not only cloning classic amps, but provides a new world of unimagined tones as well. The AMP CUSTOMISE function lets you mutate classic amps beyond.

Simple & Intuitive User Interface

The GT-100's unique dual-LCD and eight-knob user interface provides fast access and intuitive control. There are no menus to navigate; every function is instantly available. The tone-customising functionality has been improved as well. All patches, amps, and overdrive/distortions can be created from scratch and/or customised with the friendly graphical TONE GRID.

New Tonal Possibilities

A new dimension of expression is available with the ACCEL pedal, which enables control of multiple parameters simultaneously, as well as time-variant effects such as FEEDBACKER, S-BEND, TWIST, etc. Experiment with creative combinations of parameters, interacting in real time with the pedal.

New A/B Channel Divide Function

Another notable new feature onboard the GT-100 is the versatile A/B Channel Divide. Assign different amps and effects to each channel, and divide the signal not only by dynamics, but by frequency as well, with each channel capable of driving its own effects and amps settings. The range of tonal possibilities gets wider, and wilder. Assign smooth, mild lead tones to the mid-to-high pitches, for example, and heavy, cutting tones to the lower notes.
