Picked up a used model as Boss has discontinued these. Got home from work and had about 30 minutes to play with it some before having to leave. First impression......it doesn't "sound" like a pedal. With bass, middle, treble, and presence control(s) along with gain and level, it's going to take a little time to dial in, but first impression....I like it, a LOT. I didn't think it was possible to have a pedal MORE subtle than my Timmy, but I was wrong. First Boss pedal and it's built like a tank.
