I'm hoping someone can help me. I just picked up a used 2002 Jazz Bass and I'm having a nightmare getting the intonation set on the E string. When I play the 12th fret, my tuner shows flat regardless of where I set the saddle. I moved the saddle all the way to the front and it didn't help a bit. Then I listened to the bass plugged in and noticed that from about the 10th fret and up the notes sounded out of tune with themselves. What I mean is, I play only the 12th fret (E) and I hear two pitches, very out of tune with each other. I guess that's common with bad intonation, I've just never heard it that bad before. Any ideas? The neck seems ok, and the other strings are fine. I even tried replacing the string and swapping the bridge, but neither helped.
