Hi, I have an Epiphone Les Paul Standard the hole where i put the input jack keeps breaking, the nut keeps falling off causing the hole to push in to the guitar whenever i try to plug the jack in.

Any suggestions? I've tried screwing the nut back on plenty of time but it just keeps falling off after a while.

Help most appreciated

Locktight. I have this problem occasionally with my LP.

But locktight should fix the problem.

It's only a few USD, and you can buy it at just about any hardware store.
Just let the good times roll.
even high end guitars have this problem
its like ultra common
just tighten it up but make sure you dont twist the wires inside tho, i did that with my first guitar and had to get it repaired
