Unless you provide a picture, the bass does not exist. It is impossible to replace parts on an invisible bass. Especially if you don't want it getting scratched or dinged up.I bought a Fender Jazz bass in 2009 and can can't tell what kind it is. It's made in USA. Serial number says it was made in 07/08. I remember the sales guy said it was some kind of special edition. It has three knobs but the big nob had a little knob on top of it. I don't remember what it did. Its since fallen off and I can't find a replacement for it. This is why I am trying to figure out what kind of bass it is. Anybody know?
