You get 4 channels:
Rhythm (Rtm): Impressive Clean through some low gain tones
Rhythm Boost (RtmBst): Classic rock tone, less bass than lead channel and great with both humbuckers and single coils.
Lead: Nice, fat tone. This is a great modern rhythm guitar tone!
Lead Boost (LeadBst): This is what most will come for! Thick, rich tone that has immediate attack and endless sustain. These amps cost a ton of money for a reason. This channel is that reason.
