Ok, so I'm not a luthier and have finally watched/read enough material that I thought I could do my own set-up. For the most part, I've succeeded. This is a brand new Fender Precision Special. I took some relief out of the neck to where the action was acceptable to me, raising the action on the E string a little so that it didn't buzz. I also tried to intonate the bass with my Korg rack mount tuner. I realize that I really should get a strobe tuner, but I think I'm very close. Anyway, the G string seems to have a dissonant sound on the fifth fret, as if it were a little flat maybe, but I don't think it's that. Maybe the frets aren't quite level? I really don't know. I suppose I'll have to take it to a qualified person to figure out. I'm really please with how it plays now, except for this issue.
