I have a fender jazz bass with a badass II bridge. I think it plays and sounds very good. There is no fretbuzz anywhere on the neck. But I've noticed that the strings seem somewhat off center. That is, instead of the position marker being directly between the A and D strings, it's closer to the A. That leaves only a little bit of fret under the G string. Also, the strings aren't exactly over the pickup poles, but slightly to off. Is this a problem? If so, how is it fixed?
