Boss GT-100

The GT100 is a very comprehensive multi-effects pedal, released in the early 2010s, based on Boss's COSM modeling. It offers a huge range of amps, overdrives/distortions, compressors, equalizers, modulations, delays, reverbs, wah, pitch, and harmonizer, with two signal chains that can be separated or combined using the A/B Channel Divider system. Version 2.0 is particularly interesting: it notably adds the BGNR UB Metal and ORNG Rock Reverb models, the Tera Echo, Overtone, and A-DIST effects, an acoustic simulator, and an improved USB audio/MIDI interface.
