You know, the ones with only 2 knobs (output and distortion). I seen one of these (actually 3 of 'em) at a local ma & pa music store today for $100 each. I heard it through a little Fender champ and a Les Paul, sounded like it had plenty of gain on tap but maybe a little too top endy? What's your opinion on this pedals? Would the work in front of a Dr Z amp or an AC30 style amp? I've got 3 tubeescreamers now and i'm just looking for something a little different, but that still sounds good. I've got my mind set on an OCD, but just wondering if this is some kind of "secret weapon" of some sorts or a great pedal that nobody really knows about? Chances are, no, since there's 3 of them in the same store..... but it's worth a shot.
