Foxx Tone Machine...excessive noise and picking up radio stations.

[Nocaster Cat]

I just built out a Tone Machine and there seems to be excess noise and I'm also picking up radio signals. I happen to have a Fulltone Ultimate Octave here as well and it's much quieter than my build. I've implemented most of the UO mods (left off the Bright/Fat switch) which brought down the noise floor a little but I'd like to get rid of the radio interference. Any suggestions would be greatly appreciated, thanks.

A 10pf capacitor to ground on the input will help, also a small series resistance on the input if there isn't one there already.
