Does this work on a compressor to replace the LED and sensor?
Reading the description, I suspect no, but thought I would check....

It may. Inside there is just an LED and LDR. I'm not 100% sure on the model numbers though.

What you would want is a vactrol

That appears to be the same thing - here is the description:

Tiny audio optocoupler is about the size of a pencil eraser and has 4 leads. These are used extensively in audio compressors, audio level controls, audio limiters, expanders/noise gates, guitar tremolo effects, guitar amplifiers and music effect boxes. Inside the black epoxy case is a 2 lead photocell (not a photodiode or photo-transistor) and a 2 lead LED. This is why the device finds extensive use in audio applications (photocell instead of photodiode). The LED requires about 10-16mA current and the resistance of the photocell varies from 150K up to megohms when the LED is off to under 400 Ohms when the LED is on. New. NOTE: Dot on case marks the cathode (-) lead of the LED. Blowout price! Actual brand may vary from picture. Sold in a package of 10.

lvlark, ironic you have a bargains section. Your website is the best bargain on the web for anyone even thinking about building pedals. Thank you. How does one go about supporting your sight monetarily? A small donation from every user might pay off some medical school expenses, no? Best wishes.

Thanks very much for saying so, glad you enjoy the site.  I've never set myself up to take donations but if anyone would like to then if there are any adverts you're interested in on the main site (not this forum), then Google can always contribute for you
