ok..the nut on my output jack on my guitar keeps coming loose..anyone have an idea how to stop it from doing that?
tighten it really well, but don't strip it, or you might've already stripped it, i'd check. worst comes to worst you buy a new output jack for 2 bucks.
I generally tighten up the nut and apply a drop of superglue, you can break the seal easily with a nut driver if you have to remove it later, but the nut wont back off otherwise.
you could try a drop of super glue, but just a drop so you can break it loose if you need to take it off for any reason.
