Just received mine today. WOW! This is the one of best hard rock pedals in the modded Marshall vein I have ever played. Thick honkin' mid-range, and great harmonics on the top end! Just the way I like. You can do some serious ZZ Top pinch harmonic stuff with this pedal. Very musical on the rhythm crunch tones as well, with a really sweet top end crunch. I like it a lot better than the Crunch Box that I had. It sounds and feels more amp-like. Chad has been great as well. Smooth transaction, and very responsive to e-mails. Highly recommended!
