Hey everyone, this is my first post on the forum but I really need some assistance. I got a Digitech GNX3 Pedal as a hand-me-down, Its been kept in good condition I'm just having one huge problem with it -- occasionally it just decides that it doesn't want to stay on one effects setting. It will rapidly cycle through a bunch of different patches over and over. I have a pretty technological background but I don't know much of anything about guitar pedals. Anyone know what might be causing this? My best guess is just old wires but I'd like to try and fix it myself. Thanks!
