My new Fender jazz is buzzing BADLY, and the action isn't even very low. Do I use an allen wrench to fix the truss rod? Does the truss rod even need to be touched (it does buzz at the first fret; ideally I would like the action as low as I can get it, though I play relatively hard)? Also, I don't know how to adjust the saddle properly. Do I just use a phillips to move the thingys back or fourth? I really have no idea what I'm doing here, and the tutorials in the sticky weren't very much help. Thanks in advance for any assistance!!!
