Seymour Duncan 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 Slash's original Derrig Les Paul copy. The Slash humbucker set is hand-built in Santa Barbara the same way we built his originals in the 80s, using a nickel silver bottom plate with long mounting legs, single-conductor braided lead wire, maple spacer, paper tape, and wax potting.
