I've found a used Am Std Jazz in a local store. I'd like some help in determining if it's got the right parts on it. The neck bears a Z94 serial number, which looks like it's correct for a 2009. It has the correct tuners. The body is black, and has the through-body string ferrules. This makes me think that the neck and body are the originals for a 2009 Am Std Jazz and that nobody's exchanged these parts. What strikes me as odd is the accessories. It has the chrome pickup covers and bridge covers, but they don't seem to fit right. They're loose and they rattle, and the screws that mount them look wrong on the bass, and they're too long to screw all the way in. The action is typically high (but only a little high), but what is odd is that the strings buzz on the chromed pickup cover. I'm wondering if the pickup and bridge covers even belong on this bass. Did it come with them? Or are they likely to have come from something else? I'm wondering if the pickup covers were added to hide the electronics. Can anyone tell me which pickups are supposed to be in the 2009 Am Std Jazz, and how to identify them to make sure that the original parts haven't been swapped out? Thanks.
