Its amazing! Extremely versatile. There's Gain, Drive, and Envelope pots that give you a very wide range of tones. Everything from glassy cleans to Lynch like tones at the extreme gain side of things. Not a metal amp, just very punchy rock tones. Very adjustable, impossible to not find good tones in it. Makes your strings feel alive and very touch sensitive. Pedals sound clear and lush. Nice powered loop. Unbelievably loud for 50 watts. Just for fun, I patched the loop and cranked up the loop level. Even through my 2x12 cab it was abusively loud. Doesn't get ragged until you are very close to the extreme limits. Absolutely nails mid gain early 80's stuff. Must have for early VH, Great White, Def Leppard kinda tones. Punches you in the chest like a bass amp. Tube screamer in front gives it a meaner, near metal kinda tone, earlier Megadeth-ish.
Got about 7 hours on it since yesterday, I think it's a keeper.
