This is a simply phenomenal sounding amp. Gone are the days of just shoe-horning the contents of a head into a smaller box, throwing in speakers, and hoping for the best.

Shimmering clean would even lend to country or rockabilly when stepped on (from a Marshall?). If you tune down extremely low, and want the guttural tones of the underworld, they are also included. Not just included, exalted. Blues, no problem. Classic rock - every version thereof. Amptastic...
