From the post
The Tremulus Lune was designed by Dan Green from Commonsound and is a fantastic sounding optical tremolo. It's a very versatile trem, and has a very adjustable LFO section. The audio path goes through the TL072, and the LFO is created with the 4558. A VTL5C2 can be used, or you can make your own photocupler with an LED (3mm red) and LDR (5k/500k). The LED pads on the right side of the board is for an LFO speed indicator. This LED could easily be used as on/off indication as well. Wire the anode (+) to the board as indicated, and the cathode (-) to the footswitch (typically pin 4 or 7–refer to the General Layout Notes tab above). Then wire the footswitch (pin 5 or 8) to the LED - pad on the board.
