From the post
Apparently it's going to be a compressor week. It came to my attention that my original schematic and layout for the Deep Six had a few errors. And since I want to build this one myself and my dislike of off board wiring, I laid this out for board mounted pots. It should be a pretty comfortable fit in a 1590BB, but if you're unlike me and don't mind playing with hookup wire, you could probably fit it in a 125B. Essentially, this is a modded Ross Compressor/DynaComp based off the BYOC 5-Knob Compressor and with a charge pump. I know a lot of you like to do charge pumps differently, so I've left that off the board so you can pick your preferred charge pump daughter board. And if you want to just run it at 9v instead of 18, that totally works as well.
And here's the updated schematic for references:
