Playing it feels ok. Need to get some decent strings.

Soundwise. Not happy. The moment I turn up the tone even a little it buzzes.

First thing I'm going to do is move the connections to ground around. I suspect there is resistance in the copper tape connections, meter shows 1 or 2 ohms in various places. Wouldn't have thought it create much difference in ground potential, but it might be something. Connecting them all to the same place and also connecting the pots directly should eliminate even that small resistance.

(Didn't really notice the buzz through my amp, but in the headphone amp which relays every squeak it was very annoying.)
