This came off my first guitar, an original 1962 Sunburst Fender Jaguar, when I stupidly routed it for a Humbucker in 1982. What kids do... Somehow, when I put back the original pickup a few years later, I forgot to put this back on. Your gain!
1962 was the first year for the Jaguar. The one this came from was dated October 18, 1962.
See also the chrome bridge cover I'm selling, if you need one to make your 60's Jag complete.
