Is there such a thing? My reverb-tremolo Deluxe amp footswitch is the standard issue and the plug to the amp is a balanced 1/4 cord. Will ANY two button footswitch with balanced cord, work? I'd like to be able, at a glance, to see if the reverb or tremolo is on, especially before a song. I'm constantly forgetting to turn the tremolo OFF between songs. any suggestions?
