Here is a set of genuine vintage circa 1980s Gibson Humbuckers, this is a great opportunity to either upgrade your guitar or make good one of your own vintage Guitars. The patent number is stamped on the baseplate and the pole pieces of gold ,no covers. The bridge reads 7.7k and the neck 7.5k . Judging by the length of the leads, I would’ve said this was probably out of a Les Paul custom.
