I've noticed lately that the way i pick up my guitar affects how in tune it is. So I figured that the neck must be moving. To make a long story short, the screw holes that go through the neck and into the body are way too wide (the screws move around a lot which move the neck...). I'm thinking that I need to fill the holes and redrill them. Is that the best solution? How would I fill the holes? As always, I appreciate your help, so Thanks in advance.
