Having seen this thread brought back from slumber I brought mine out of the cupboard and put it through it’s paces. The enhance knob does make a difference but I keep it off. I had forgotten how good this pedal is, and it’s very quiet, no hiss. I never used it with a Stingray before but it sounds pretty good. I’ll keep it on the board in place of the Ampeg OptoComp, which I really like, for the next gig and see how it goes.
