Fender Hot "Noiseless" BUZZ
I had a dead quiet strat with Fender hot noiseless pups. I changed the pots to full size using Jeff Beck Wiring diagram.
I have followed it to a "T" and there is now this buzz that goes away when I touch the strings, bridge, tuners or bridge. The buzz is not a little buzz - pretty loud. Thinking I screwed something up, I bought a new switch and all new pots, new wire again - only to have the same issue. Same amp, outlet etc. The only thing I did not do is the ground to body cavity. But the previous setup did not have it and the cavity is not shielded.
I have been playing 20 years but I am a noob in wiring. HELP!!
Sounds to me like you forgot to wire up the earth wire to the trem unit.
Could also be the earth wire to the jack socket that's not connected right.
