I want/need ALL the DIY compressors.

We'd need to tweak a few caps for bass.

Goldfinger! (not verified of course)

Looks good, but I do not recommend 2N3904 & 2N3906. This circuit needs high gain transistors.
NPN: 2N5210, 2N5088, 2N5089, BC549C (reverse pinout)
PNP: 2N5087, BC560C (reverse pinout)

Thanks for looking, and thanks for the reminder! I added those part numbers as placeholders since
KiCad doesn't have the 2N508[9/7] pair. I should fix up the silkscreen before having some made.
