    Recently picked up a 2014 SGJ. intonation is fine from 1st to 12th fret, but by the time you get up to about 17-18 on up to 24th fret it's getting pretty sharp. What would cause this? Thanks

    Is the intonation perfect on the 12th fret harmonic/fretted note?
    If not, I would say flat it a touch by moving the saddle back from the pickup a bit

    That could be caused by high action. Can you lower it?

    Have you put new strings on? Setting intonation on an old worn set is near impossible. If the strings are new, the answers already given are good places to start, but if the thing still intonates sharp at the top end, try to correct it there, because the error at the twelfth will be much less.

    Action is set to spec, but I haven't changed strings on it, I'll start there. I'm not too worried about it, it doesn't get off much until 19th fret. I don't play up in that range often. Thanks for the advise.
