If you play an Epiphone upright bass you belong to a very small group of bass players that get to enjoy a fine American made plywood bass (okay, I know I just lost half of the readers, as this would be a "junk food" bass thread...) I have read several threads about the little known history of the Epi bass. Dating an Epi and looking for a serial number can be quite a task. I have found stamped serial numbers under the scroll head and at the end pin. I have read they can also be found on the end of the fret board. Where else have you found serial numbers stamped? Has anyone found an accurate source for dating Epi's year of manufacturing? Have you ever seen a paper label on the inside? Should the metal tail badge always have the model number engraved on it? There seems to be no record for the early Epi's made in NY and only limited info on the Epi/Gibson Kalamazoo, MI years. If anyone wants to chime in with their knowledge of Epiphone upright basses, please do. I think I will go back through some threads and document the serial number, model number and possible guess at manufacture year. I'll dump the info into an Excel spread sheet just for sh*ts & giggles to see what I get.
