This thing is pretty mental, frankly. Firstly, as a fuzz, you can switch between germanium and silicon transistors, 60s and 70s voicing, octave fuzz or not, edgy or smooth, gated or not, 9-18V... holy crap. Then, you add an adjustable boost before and after the fuzz. Then, you add THREE loops for FX: one that's always one, one that's engaged when the boost is one, and one that's on when the pedal is off. The SideTrak loop doubles as a dry output too... oh boy, it's mental I tell you.
