Ground wire to the bridge (Les Paul question)

A friend came over last night with a fairly new Chinese-made Epiphone goldtop LP with P-90's. It sounds and plays great, except that it buzzes like a son of a gun, and when you touch the strings, the buzz does not change in any way. I checked the control cavity, and the ground wire is soldered to the pot ok, so I am guessing that it isn't making a connection to the bridge. The wire disappears down a hole that probably leads to the lower insert for the stop tailpiece. On a tele it is easy to fix this, but I am wondering if on an LP you have to remove the threaded insert to get to the wire connection. Has anyone done this?

Thanks,

John

I fixed that problem by sticking a straightened paper clip into the hole as far as I could and then rested the other end on one of the pots.

With a drop of solder, I was in business.

Just pop that threaded bolt out of the body. If its a solid core ground wire, make sure its being sandwiched in tightly by the post. If its a wound/threaded wire, try striping some insulation of the tip & fanning out the wires a little. That should ensure contact w/ the bridge, thus properly grounding it.

Thanks for the responses. I'll try that out
