Awesome pedal, huge range of tones, and of course it does the Sleep thing too. Used as a desktop preamp, it worked great with cab sims and stacking with other pedals, but just by itself into the front of a gritty amp is massive. Runs on 9-18volts and has the best components and one-off build quality that blows away the original. $99 cash or trade for other pedals (not seeking particulars). No shipping/delivery.
