Just the pedal on/off LED and a preset around there, not an optocoupler
LED/VR combination

Unfortunately I don't have it here yet. Probably holds the LED on at switch
on for a few seconds, for confirmastion otherwise no function. Then LED only
goes on when the compressor is activated via the stomp switch
