Check power supply? Try battery instead? Weird oscillation. I don't see how the pedal could be doing that. FYI, was looking to buy this pedal used now I'm balking!
Had to get center negative power supply for it to work after contacting company. This video was with AC power supply. It does t come equipped with one so you must get the right one. I will test it soon on an Ibanez as the fender Squier also created issues sound wise.
