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 Slash's original Derrig  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.
