I've got an Ibanez SR496 6-string. Fairly low/good action. I don't have what I know as fret-buzz, since I don't hear any frets buzzing on the fretboard (knock on wood...). On the other hand, when I put my ear to the "horn" of my bass and play it un-amplified, I hear a distinct buzzing (physical/mechanical, since the bass isn't plugged-in) on some notes. 3rd-fret A-string is especially bad. The buzzing, when I listen closely in a quiet room seems to be coming from the body of the bass, in the area of the pickups. I loosened the pickups, and jiggled them around, but it didn't make any difference (didn't remove them, since strings were still on). I also opened-up the electronics/battery cavity, but didn't see/hear anything there. I'm kind-of suspecting the bridge, since the sound does not SEEM to be coming from the neck (truss-rod or frets). Question: Before I buy a new Hipshot "style A" bridge, can the apparent source of vibration on a bass "fool you"? Might I be hearing what is really neck problems (truss or fret), even though it sounds like the vibration comes from the center of the body? I don't really want to spend money for a luthier to work on the bass - it is only a $600 bass. On the other hand, I don't want to invest over $100, and risk messing-up the bass if the chance of this being the problem is in question.
