Re: Locking nut doesn't lock the strings.Help needed.
Let's clarify, if the tighten the E/A bolt, the bolt does tighten?? Because if the bolt tightens it should lock the strings in the nut.
Now the loose nut screw, use a cut E string, medium gap filling CA, and accelerator, run around the inside of the hole, accelerate. let dry. Sometimes you will have to do it twice to get a goot grip on the screw.
If these are the old black screws, stop. They're twist in half. They should be the chrome pan head chinese screws, be careful you don't strip the top +, the screws suck.
