    As many people are aware, fender headstocks/necks have an age old problem of dead spots on the G string round frets 5-8. On fretlesses it can translate to the same notes on the D string round fret positions 10-13 as well.

    I know the cures, but surely the cause is better found.

    Was wondering, has anyone done some serious research into the cause? Has the specific problem been found?

    It's caused by an antinode of the a particular resonant frequency of the neck beam falling at the same position as the fret where you fret a string to produce that same note, or a related multiple of the frequency. There's a paper that showed vibrational analysis that backed this up.

    Yes it's not at a position on the neck but rather at the frequency produced by the note in this position.

    The problem is also not isolated to 'F' style necks or even just to bolt on's. Even though they are more prevalent in that kind of design, I have a deep set neck bass with an angled headstock that also has a minor dead spot.
