Fred Forsell's Opto Sidechain
...to become a full opto compressor one day!
It all started with a [discussion] at ["the Lab"] about a small and fine design by [Mr Fred Forsell] for a [opto compressor sidechain]
The idea evolved...
So far we have:
Side chain
Mr. Forsell contributed a PCB Layout ...
[PDF] (external link)
..., the gerber files: [ZIP] (external link) and
... and a complete schematic

M. Nats contributed another PCB layout:

Amp stage
Buttachunk contributed a makeup amp stage stage:
New version (will sound cleaner):
Buttachunk's old version (will sound darker):
