HELP! My favorite guitar is buzzing super loud!

[marshallH]

This should be an easy fix, but I don't know what to do. I could switch out the pickup but the on,y pickup I currently have is 1981 Tim shaw paf and while that is an amazing $400 pickup it just happens to be broken and I don't want to buy a new one. Anyway, I know that it's the guitar and not the amp because none of my other guitars buzz in it. Would foil shielding help? If so, how do I do this?

EDIT: no, the one buzzing is not my brand new super distortion 7, it's a realiable pickup.

Double EDIT: the input jack has been having some problems with it coming loose, so I assume it's a jack problem.

Here is the jack and guts

Try rewiring everything to see if it's just a bad solder joint.

I second checking the connections. It could be a bad/cold solder or possibly a loose or improperly grounded wire.

loose solder to the bridge? That joint is most likely to be the weakest.

The ground and hot wires to the jack could also be switched, but I can't remember off the top of my head if that would make loud buzzing sounds or no sound.
