From the post
The Walrus Audio Deep Six is a versatile compressor that gives studio level compression in stompbox form (that's what their website says, anyway). It's very similar to the BYOC 5-knob compressor, with the only difference being a few component changes in the blend and output stages. I set out to try and make a layout that would fit in a 1590B with on-board pots. Let's just say there's a reason most circuit boards today are at least double-sided. You could board-mount the Ratio and Level controls if you want (use right angle PCB pots mounted on the solder side) and in theory it should fit in a 1590B, but if it were me, I'd put it in a 1590BB and give myself some elbow room. Most 1µ caps are laid out for tantalums to save space and reduce noise.
Here's the schematic I drew for reference.
