    I noticed that my open E is in tune but out of tune at the 12th fret. Is this just bad intonation set up? Is the bridge saddle positioning the problem? It's not on all strings so I don't suspect the nut or fret positioning.

    Yup it's bad intonation setup.
    You can check it like this:
    Tune the strings with the harmonic at the 12th fret.
    Then play that harmonic and compare it with the fretted 12th fret note.
    If the fretted note is sharp you need to move the bridge saddle back (away from the neck).
    If it's flat move it towards the neck.

    Do it on all strings, and repeat it til it's ok. Whenever you change strings you should check this.

    But remember that intonation is never perfect for all frets. This method is just a good approximation.

    To find more threads on this topic, search for "intonation". We've been over it a half-dozen times recently -- you'll find TONS of good information here.

    You also need to recheck your intonation after any other setup change such as truss rod or saddle height (action) adjustments.
