I would appreciate some comment on the effect of the contact area in a bolt-on neck joint (sorry if this has been done before, but a forum search didn't find anything). First a disclaimer - don't try this on your own bass unless you know what you are doing. I have a USA Precision that is a really nice, resonant bass (maple/rosewood neck, ash body) but had a bit of a dead spot on the top G string, 5th fret, not something I really expected in a graphite-reinforced neck. I risked pulling the neck to check the joint and found the join was essentially bits of paper with bar codes and dates. Do Fender use sticky paper to help assembly? Anyway, all this was carefully removed (and kept) and surfaces cleaned up. I didn't go as far as removing the finish for a wood-on-wood joint as Godin claim they do for some of their guitars. On re-assembly the dead spot was all but gone. So one of my favourite basses is now better than before. Or am I imagining all this? I think physics says that waves are best transferred between surfaces with identical properties (propagation velocity?) so could it be that the paper labels were reflecting back vibration and nulling certain notes? I don't have much experience with these things so I would certainly appreciate comment from the experts out there.
