I'm trying to do some research on dead spots on guitars. I've searched here, and found that lots of people complain about a dead spot on their strats/teles around the 12-13-14th fret on the G string. This sounds like more than just a coincendence. Is there a reason why a dead spot can occur here quite frequently? The way the wood vibrates on top of the big bots underneath? Poorly seated frets? Poorly slotted nut causing sympathetic vibes? Or is it just bum wood? Or IS it just a coincedence?
