I have a Super Reverb Reissue, and for as long as I can remember, only the "Vibrato" (tremolo) footswitch works, the Reverb footswitch does not. I thought one of the switches was bad, so I replaced both footswitches with higher quality footswitches. Still didn't work. Tried a footswitch from a Deluxe Reverb Reissue, still nothing. Does that mean the footswitch jack or the relay needs to be replaced? Luckily it is stuck on, so I can control it with the knobs if I need to, but would love to have foot-switchable control again, especially since I have an Eventide H9 now that I will be using for some reverb action.
