First impression is good. The pedal looks and feels solid, in its metal casing. It is rather versatile in the variety of distortion sounds one can create using the voice dial. It's supposed to create Mesa Boogie-type sounds, but I'm not familiar enough with those amps to comment. I bought this pedal based on sound examples on You Tube. Having said that, I've tried it going into a valve pre-amp and into the power-amp, and I haven't really found a sound that I like. Some overdriven sounds are pretty decent, though. Maybe it's the amp modelling that makes it sound somewhat muffled and compressed... I'll keep trying, though!
