If you have an okay sound on clean channels, and a nasty humming on overdrive, and that gets louder when you touch the strings, then check your jack. I had the wires reversed. Switched them to the correct positions and now the hum is gone and the sound is great! I played the National Anthem on the bridge pickup with full overdrive and a bit of distortion on the pedal, and smiled all the way through it....now I'm really determined to polish it up and fix those finish and screw problems.
