Hi...I have a Kustom Quad 100 DFS and a footswitch to go with it. When I plug the footswitch in, it does what it should as far as not let you switch manually on the amp and the lights on the footswitch light up but when you hit the either the channel or the effects switch ...nothing happens....you can still hear the guitar in the setting you had it in before plugging up the switch but you cannot change it with the switch. Any thoughts?

I would like a wiring diagram/schematic for the kustom kac fs201 footswitch so that I can trouble-shoot it. If there is a problem on the Amp Board I'll definitely need some help there
