Looking forward to seeing how this one develops. I use a compressor pretty regularly.

Fired the breadboard rig up through an amp for the first time yesterday.

It does work, so there is some basic happiness!

The attack time is too long - the leading edge of the note (about 20ms) isn't compressed so you get a "click" at the start of the note. The attack time is dependent on the "rise time" of the LDR (Light Dependent Resistor) in the optical coupler. I've ordered a faster LDR that will hopefully fix the problem.

In the interim (while I mess with a circuit for my own compressor) I've been using my new-to-me Aphex Punch Factory.

It doesn't get much love - I don't know why. It is optical, and nicely transparent.

Ive just ordered a Eklipse parallel optical compressor from Dev Tech Audio in Australia. Purportedly a Cornish OC-1. It will be dispatched in a couple of weeks. I bought it on the strength of this video

That looks and sounds pretty good! Am very tempted... What did you pay for it?

The Aphex is a nice pedal, but does lack a little feel. I use it mainly to feed my EHX B9 - the B9 needs a relatively constant signal to work well.

219 AUS + postage

he is a few weeks behind in orders

he makes a bunch of Cornish clones at very reasonable prices

I picked up one of these (a Cornish SS-3 copy) a while back. I think they are a limited run, its very nice

I'm on an Australian-built kick at the moment

So I think I have my final compressor ... Picked up a good deal on a Strymon OB.1

No need to design my own - this is essentially what I would have done.

Looks cool.
Possible Infringement, or something?
