The GT-100 is Boss's flagship floor processor, loaded with next-generation COSM amp modeling that faithfully recreates classics like the Fender Twin Reverb, Marshall JCM800, and Mesa Dual Rectifier. The dual-LCD and eight-knob interface means no menu-diving: every parameter is right there in front of you, ready to tweak in real time. 400 program memories give you plenty of room to build a library of tones.

The Accel expression pedal lets you control multiple parameters simultaneously for dramatic sweeps and transitions, while the A/B Channel Divide function splits your signal by dynamics and frequency so each channel can run its own amp and effects chain. An XLR mic input with phantom power covers acoustic-electric guitar, stereo effects loops integrate external gear, and USB connects to the Boss Tone Studio editor. 24-bit conversion at 44.1 kHz keeps everything sounding pristine.
