About This Model
The Boss GT-100 is a flagship guitar multi-effects processor built around Boss's Advanced COSM amp modeling engine, delivering 44 effect types - including distortion, chorus, delay, and reverb - with 24-bit AD conversion and a 44.1 kHz sampling rate for studio-grade audio quality. Its A/B Channel Divide system lets players run two fully independent amp and effect chains simultaneously, while Amp Customize and OD/DS Customize modes allow deep tone shaping from the ground up. With 400 program memories (200 user, 200 preset), a built-in looper offering up to 38 seconds of mono recording, a dedicated ACCEL pedal for real-time multi-parameter control, and comprehensive I/O including USB, MIDI, and stereo outputs, the GT-100 is engineered for both live performance and studio use.
A great opportunity to own a Boss GT-100 at this price point.
