I have a very frustrating issue on two build I have completed wherby i have serious buzzing from the electronics. Now i things its down to a bad earth but not sure, you can here the grounding on touching the bridge etc. Now i have checked the following
1- Bridges are both earthed and earth wire is on tone pot (earth is soldered to the bridge)
2- All pots have earth wires going to them in loop (except last pot)
3- I dont think i have any dry joints (how can you tell)
I though I may have fried a pot so have changed this but still the same problem. The only thing i have not done on one build is shield the cavity but on one all cavities are shielded with foil.
1st build = tele style with twin seymour duncan hot rails (no coil tap) into a normal 3 way tele switch. 500K pots 0.22uf cap
2nd build = tele style with twin S/D humbuckers coil tapped only, way switch, 500k pots with 0.47uf paper in oil caps
Help needed please

If so it's a shielding issue, not a grounding one. The bridge is earthed, so when you touch it you're earthed too and your body acts as a shield.
would you recommend the shielding paint or foil tape for best results.? i have foil taped the build with hot rails and it is still buzzing
thanks for your input
Oh nice workshop build thread btw

I've only used paint for shielding. I think either will work fine, it's probably about personal preference - which you find easier to apply.
I'd check that the foil is grounded if you're still getting buzz - probably obvious, but sometimes rechecking all the obvious things gets you there.

I recently re-shielded an active bass which had paint shielding, using copper tape, because the paint wasn't doing the job well enough. It made a very noticeable improvement.
