The Seymour Duncan SSL-1 is a vintage-correct reproduction of the original Alnico V Stratocaster pickups. The same type of magnet wire is used, as well as the same number of coil windings. The staggered rod magnets are hand-ground, then aged by the exclusive Dun-Aged process, lacquered bobbins and cloth-braid hookup wire complete the vintage look. Every detail is included to duplicate the bell-like tone and the high-end bite that made the vintage Strat famous.
