While testing the switches on the dirty channel for tone on the back of the module I loaded up my syn 30 and tried to go back to the clean channel and it does not engage the clean channel. when manually changing the channels on the amp it will click as if changing channels but the clean channel light is dim and does not engage the clean channel. it is actually on the BE channel and the clean channel is non functioning. It was working fine but while testing the switches I had to uninstall and reinstall a few times. The module fits tight so I was being careful. so what has happened? Also I installed my HBE module and it is fine. Green light is bright and switches good.
