I demoed this pedal the other day at Guitar Center. Played through a decent tube amp with a Gibson LP.... all I can say is this thing thoroughly confused me. It was near impossible to get a usable sound. There was something wierd and unnatural about it... maybe the fact that the tone itself sounded like a fuzzy distortion, but there was not much compression/sustain that I normally associate with that type of distortion. Very strange pedal... or I don't know how to use it.
