Grey Compressor

So I recently got my hands on a super-rare and super-expensive optocoupler from an estate sale. And I promptly broke it. I was pretty excited about having the opportunity to make a compressor or wah pedal, so I got some LEDs and photodiodes to make an equivalent to the optocoupler. I ended up building this simple compressor pedal that has the same color scheme as a Keeley compressor. The similarities stop there, from what I can tell. There are some weird scratchy sounds in it, so I’ll have to clean the pots and maybe replace components that include silicon.
