Hello, I bought the Acoustic DSP 120 at a local pawn shop for $89. So far it sounds great and i've been getting clean tone with no feedback considering how cheap I got the amp for. I'm fairly new at playing with a large amp with multiple features so if somebody has this amp, that would be great if you know some good settings for hardcore/punk, rockabilly, and blues. I have a Boss DS-1 Distortion pedal and a Boss ME-50 so those pretty much get me to a similar sound but not quite what i'm looking for.
