How1 Posted April 29, 2023 Share Posted April 29, 2023 (edited) I’ve been getting a lot of noise from my Precision, so this morning I decided to shield it. I’ve covered the cavity in copper tape and attached a strip from the cavity to under the pickguard which is also shielded. It’s all one cavity, no separate PU cavity. I’ve also checked the bridge wire and added a bit of tape. It doesn’t seems to have made much difference. Do I need a wire going from the ground on the jack socket to the cavity? Or the bridge to the cavity? I’ve done all this once on a different bass and can’t remember exactly what I did.

How1 Posted April 29, 2023 Author Share Posted April 29, 2023 (edited) Brilliant, sorted (kind of). I’ve at least narrowed it down to some pickup/pole piece noise now. That’s a job for another day. Edited April 29, 2023 by How1 Quote Link to comment Share on other sites More sharing options...

The copper shielding needs continuity to the Screen (Ground) connection on the output jack. The bridge should already be connected to the jack socket screen connection (check it anyway with a continuity tester / DMM). So cavity to jack socket or to bridge will have same effect in practice. Without a connection the copper screen is just 'floating' electrically and effects are unpredictable. Quote Link to comment Share on other sites More sharing options...
