    Hi all. I was just wondering if anyone could explain the purpose of the wire hooked up to the screw in the body. I knew this was common in cavities that had shielding paint, but what purpose does it serve in an unshielded cavity? Wouldn't the typical P bass wiring suffice? Thanks.

    Maybe that little screw and wire connect the shielding paint to the electrical ground.

    But there's no shielding paint. Maybe the metallic finish?

    Ground screws serve absolutely no purpose in unshielded instruments, unless they are being used as a point to connect many grounds in a star configuration. That is not the case here, however.

    That's what I figured. I wasn't sure if there was a remote chance it had something to do with the paint. It makes me wonder...if my 2012 isn't shielded in the cavity, than why the hell are Fender wasting wire on this config? There's an additional wire from jack that isn't in the photo as well. I kept looking at the wiring and wondering why it was the way it was.

    Are you sure that it isn't shielded? Perhaps they painted the body after shielding?

    Is that an accepted practice? If so, that would be the explanation I suppose. The underside of the PG has the usual strip of foil, than the extra wire leading from jack to tone (or vise versa) and the ground lug. Is it possible to apply shielding paint under a normal paint job?

    I believe all U.S. model are shielded. So I suspect they in fact painted over it. You could easily check by scraping a little paint off and see if its black underneath.

    it is indeed shielded under the paint, so leave that grounding screw attached to do its job.

    thank you sir. i guess the paint helps protect the shielding . good thinking imo.

    Why would you paint over the shielding paint. That makes absolutely no sense.

    Couldn't the bridge ground wire be directly soldered to the tone pot? In this setup, the bridge wire runs to the jack, than another wire is run from the jack to the pot. Is there a benefit to this setup over directly soldering the bridge ground to the tone pot?

    Beacuse it's quicker/cheaper/easier, typical Fender MO.

    They don't have to be so neat about applying the shielding paint, and the completed job looks better/prettier.
