Unique pedal design which is saying something in the day of clonation. Best used in a loop. A little thin out front. Narrow range of usable sounds, but several sweet spots to choose from. Also blends well with distortion. This is true bypass and is not a tone sucker. Comes with power supply. Digitech stuff requires alot of current. Not for sure why, but I think they step up voltages in alot of their pedals. They sond that way anyway...
