Post knob controls the volume, Pre controls the gain, Bright control adds more bite as you turn it up. The Premium sounds like a very natural amp gain. It's open and raw, gets great feedback when cranked, and stacks very well. These are nowhere in the realm of TS overdrives, so if that's what you want, look elsewhere.

Warm and bluesy, saturated full stack crunch, bright gain boost for solos... it's in there.

No buffers, True Bypass. 9V battery or neg. ground DC jack.
