I have a sparkle drive that hasn't been turning on and off properly... When ever I push on the pedal the sound cuts out ALL the way and then comes back on when I have removed my foot. So put simply when ever the footswitched is being pushed down there is NO sound. I run it in a looper anyways sooo... what should I do.. Will they fix it for free. HA. Im not the original owner and couldn't tell you how old it is.
