You think you know it all about Fender basses? If you're talking "vintage", nothing can beat the elusive 1879 Fender P Bass. This is the "missing link". Lol. Not sure what kind of amp or contraption they played that through in 1879. Hurry, get it while you can. It's apparently a one of a kind, and not another like it.
