Hey guys, I am hoping someone can help. I have had a shortboard for quite some time now and it has now developed a few bugs. The wah pedal will randomly switch back to volume control and the stomp pedals become delayed/stop every once in a while. As far as I can tell the stomp pedals begin their downward decent (become slow to respond and eventually stop responding) after using the wah pedal. Has anyone experienced this or have any suggestions? Thanks
