So this is the deal; I've got this Fender Jazz with a neck problem, which I'm assuming is due to the trussrod. The neck looks like it has too much backbow, so I tried tightening it up a bit, but that didn't fix anything. Notes above the 9th fret would buzz horribly, until I raised the string height. This fixed the buzzing, but left me with incredibly high action. How can I get the action to what I'm looking for, but still keep the buzz away?
