I just bought this, used/like new from a TBer. I have to say I am really digging this thing! It was super easy to set. I set the volume to unity and the drive at 7, then played a quick slap line. What came out of my ash/rosewood Jazz was a big, warm, tight, snappy, crisp Marcus(esque) tone that I had only come close to, before. The highs on the pops are incredible. I know the compressor guru, Bongomania, doesn't speak highly of this pedal, but for me, it sounds great. Very nice!
