GT-100

COSM Amp Effects Processor

HIGH-END AMPS AND EFFECTS FROM VINTAGE TO MODERN WITH ADVANCED FLEXIBILITY

With the new GT-100 Version 2.0 update, BOSS's flagship multi-effects processor is now even more powerful than before, with the addition of two new amp types, cutting-edge MDP effects, an acoustic guitar simulator, and an improved rotary effect.

A convenient Guitar-to-MIDI function is on board as well, letting you have fun with Guitar Friend Jam and other computer software using your normal guitar. The GT-100’s USB audio capabilities have been expanded too, providing greater flexibility for re-amping applications.

With the BOSS TONE STUDIO software, you can now edit GT-100 patches from a friendly graphical interface on your computer.
