Hey all, A few weeks ago I had my Ibby set up to eliminate the fretbuzz and truss rod problems that had developed once the bass had...acclimated? Not sure if that's the word or not...but once I 'broke it in' shall we say. Ok, so I got the bass setup, and it plays beautifully. Only problem - Very poor intonation above the 12th fret. Ordinarily I wouldn't think twice about this, but I got this bass setup by Jim Rubio from the Atlanta Bass Gallery, and I don't think this is something he would let by him. I just started noticing it, so maybe it's gotten worse since I've had it home. I'm a little bit cautious to mess with the Mono-Rail IV bridge saddles, but this intonation (or lack of) is really starting to bother me. The open strings are perfectly in tune, as are the 2nd harmonics (12 fret), but fretted notes are just off. I have to bend the string to get an in tune octave above about fret 11. From what I read, this is a bridge problem, not a truss rod one (it plays like a dream). I think it's something like 'if the 12th fret is sharper than the harmonic, move the saddle back. Flat, move it forward.' I may have it backwards. I'm worried to mess with the bridge though, because I don't want to mess up the great action. Any thoughts? Should I fix it myself? If so, could I get some help here?
