Read some older posts… so I have to clear that I’ve always used the original “Boss/Ibanez” AC Adapter, never changed it, never opened pedal or moved trimmers… simply, the pedal decided “himself” not to work properly… I’ve tried also with other power supplies (T-Rex Fuel Tank Junior, 9V 120mA), but the pedal still goes on, but no delayed sound comes out apart of dry signal… and still only “blend” and “gain” knobs works… please someone helps me!!!
