Hello Everyone! I've been recently experiencing some issues with my spider valve hd 100 mki head, and I was wondering if any of you have experienced similar problems or might have an idea as to what is going on. Basically, i play in a ska/punk band, so it requires a lot of switching between my clean and distortion channels with my pedal. Sometimes, when playing live, i will go to execute a channel change with my FBV express pedal, and it will either not switch channels at all or switch to a random channel. If i flip the amp on and off again, it will temporarily solve the problem. I took the cable and pedal into guitar center and was fooling around on some of the solid state line 6's for an hour/hour and a half with no problems at all, so i can conclude it is not the pedal or the cable. Any suggestions?
