I just picked one of these up, mainly looking for the big/heavy/distorted tones they are known for. Most of the stuff I've read on line (except for on this site) seems to peg these amps as "one trick ponies" or "only good for heavy music." Obviously these guys never bothered to turn any of the damn knobs. The variety of sounds on this thing is great. The reverb sound is freaking phenomenal.
I know I'm probably preaching to the choir here, but I could not be happier with my purchase. Now if only I could get a footswitch...
