Ok, cool, thought I was crazy.
I built the layout on the main site and it's super noisy and Im trying to wrap my head around it or built another layout altogether...

Did you box your build yet? I’ve had some builds where the transistors act like antennas when the board’s out in the open. Crazy loud. As soon as I box them they’re quiet. Just a thought.

Sorry I forgot to check, but I finally had a chance to look today. I built this exactly as the image shows. With that capacitor connected to... nothing!

It’s part of the voltage doubling circuit, not the audio path. So I’d just omit it. I’ve played the pedal and nothing’s blown up. If I had to guess, I probably took the doubler circuit from more than one place, and in combining them, I left a phantom capacitor in.
