Found a guy that's selling a MIM fender p-bass (not a squire, I checked with the seller) and 300W amp for $400. I'm always looking for the cadillac at the pinto price...so it sounds like a good deal and I'm ready to take a look at it. The real deal in this package is the P-bass. Is there anything I can look at that will help me know its real? Serial number on the headstock right? Should the number be in any particular format? What about head shape, logo etc?
