Here’s a PCB and Layout for the Ring Modu-Matic. I have yet to build this yet so use these files at your own risk! The dual gang pot in the lower corner I can’t get rid of, due to my lack of skills with Eagle. Notice the lines connecting the pot to pads on the PCB.
*** edit: These schematic and PCB had some errors. It’s been removed. There is an updated version the next post ***
