Alright, so I've got the action at a reasonable height. About 2/32" at twelve on the E, and slightly lower on the G. I still get tonnes of buzz above the twelfth fret though, even though I've tightened the neck. In fact, I think if I turn it anymore, it will start to have back bow. But that upper fret buzz won't go way. It happens a lot on the A string, slightly less on the D, and on the G only when I bend. So what's the deal? Should a fifteen-hundred dollar bass be doing this? Graeme P.S. If you'd like, I can provide some pictures to help illustrate the problem.
