When Slash was given the honor of having a Gibson Les Paul Signature model built, we sent over the same Alnico 2 Pro humbuckers that he has used for decades. Turns out, the new guitars sounded noticeably different than the original. So, we accepted the challenge to make him a new pickup that would make all of his new signature guitars sound just like the original AFD Les Paul. The result is the Slash Signature Model humbucker. We used a different mag wire and winding spec that, when combined with the alnico 2 bar magnet, provided exactly what was needed to push a stock Les Paul toward that familiar sustain, crunch, and midrange that was so characteristic of the tone of Slashs original Derrig Les Paul copy. The Slash humbuckers are hand built in Santa Barbara the same way we built his originals in the 80s, with a nickel silver bottom plate with long mounting legs, single conductor braided lead wire, maple spacer, paper tape, and wax potting. P.S. In case you were wondering, yes, the set that you buy is exactly the same as what Slashs mighty tech, Ace Bergman, installs in Slashs guitars. When the boss needs some new APH-2s, we pull them right out of production stock.
