transistor

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

Well it looks like it latches or helps with latching the LED indicator on or off when the momentary footswitch is pressed.
