Thought you folks might be able to help. A local music shop has what is supposed to be a fender jazz bass stack knob reissue. How do I know it's authentic? It is sunburst, stack knob (the tone knobs "click" if you know what I mean), has the fender logo on the headstock face, big tuners with no brand name, and the neck plate has a v number but doesn't say Fender on it. The things a bit beat, but he is asking a reasonable price ($600), but I just want to make sure it is what he says it is. Thanks for any help!
