Title: Shielding/ground loops
Post by: Snikch on May 25, 2008, 07:11:39 PM

I’m in the process of shielding my tele following the methods shown on  http://www.guitarnuts.com/wiring/shielding/tele.php.

My question is…

 my tele has a P-90 in the neck position which has braided wire coming from it, if either the braided wire or the screws that hold the P-90 in place come in contact with the copper shielding in the cavity will this cause a ground loop?

Thanks guys

No, I don't think so.  If it comes into contact with the shielding (and therefore with ground) I don't think it'll do any harm at all.

I can't claim to be any kind of expert, but I think they're a bit obsessive about ground loops in that article.  It's not a problem I've ever encountered.

if it is causing an issue just get some heat shrink tubing to put over the braided wire

OK cool, I'll see what happens and address if needed.

Thanks alot.

I can't imagine ground loops ever being a problem in a guitar, there just isn't enough ground current imo. Now when connecting two amps together, that's a different story.

nah, they can be an issue - a really annoying one sometimes

The problem will come if the braid touches a switch lug or something, then it will short. I had the same problem when having a braided MQ in the neck of my tele, ended up gaffa taping the length of the cable...
