So I have an old 80s guitar, and the neck creaks a little bit. I have a method of repair that would involve, more or less, using slightly larger screws, since one of the neck screws is loose, and the neck plate isn't flush with the body. A luthier, that I've never used has an idea that involves filling the holes, and redrilling the holes. I hear "filling holes" in a neck pocket and am a little concerned. Hundreds of pounds of pressure? on a neck pocket? I predict a glue and sawdust compound to fill the holes? Is that safe?
