Some intonation problems

    Hey everyone,

    So my bass (Warwick Corvette Std 5er)'s intonation is a bit out of whack.

    I followed the instructions on the bass setup site, and I adjusted the bridge so that the open string and 12th fret are in tune in all strings. Now, the problem is that when we get up to about the 15th-16th fret we start getting quite noticeably out of tune, and it gets worse as we go up, all the way to the 24th fret, which is borderline wrong note.

    Does this mean my neck is pretty warped? Is my relief wrong? I've checked my relief with the instructions on the website as well, and the relief is just about perfect. Should I adjust to the intonation so that a different upper register fret is in tune?

    What you want are the 12th fret fretted note and 12th fret harmonic to be the same when the bass is tuned to pitch.

    1) tune it up using the 12th fret harmonics
    2) play a string fretted at the 12th fret and watch the tuner
    3) if the tuner says the fretted note is sharp move the saddle away from the neck; if it says the fretted note is flat move the saddle towards the neck
    4) repeat 1-3 until the tuner says that both the fretted note and harmonic at the 12th fret are good
    5) start on your next string using the same sequence

    Ahh, alright. I'll do that, thanks.
