Hi all. As per some recommendations on another thread I've upgrade pickups, tone/volume pots and installed a 4 way selector to my Tele. I've wired everything using the attached image. I'm 100% correct with my wiring but I have an earth problem as in, noise when I'm not touching the guitar and no noise when I touch metal parts. The problem stops when I turn the tone to off.
The diagram does not show an earth going from anywhere to the tone pot so I soldered an extra earth from the volume pot to the tone pot but the problem still exists.
Any thoughts or suggestions? Thanks.
