Re: 50th anniversary limited edition pickups
The Musician's Friend pickups were 50th Anniversary Engraved Seth Lovers.
They had two models, one with AII magnets. The other had A5 Mags. They were sold as a bridge/neck combo, and were basically a slightly hotter version of the Seth Lovers, but with engraved covers.
Also, the set I have are double creme. Look damn good without the covers.
