Who doesn't love a good riddle?
I am kind of dumbfounded. It is a Guild neck, and an old Guild bridge. The back of the body looks like it was a 301/302, but the front looks like someone wanted a Rick. Nothing is that close up, and not a good pic of the headstock face either, so it is hard to tell. I suspect someone gutted a 72 EB3 though.
I love the Guild Kalamazoo factory line. That is a new classic. I never get tired of the Fenders and Gibsons that show up with the rare factory refin. Ah, the good ole days, when Gibson made as much money refinishing guitars for bored owners as the did making new ones! What times they were. But when there is not thread of reality at all, that is something special. Fantastic!
