Seymour Duncan APS-1 Alnico Pro II Staggered (Middle RW/RP). For Stratocaster, any position
The hand ground Alnico 2 magnets and moderate windings (Heavy Formvar® wire) yield a warm, sweet tone with more natural string vibration for great sustain. Players who get their distortion from the amp rather than the pickup love the APS-1. It allows them to back off the crunch and get beautiful clean tones with softer attack. Compared to the SSL-1, the APS-1 has a rounder sound with a spongier bass response. Comes with waxed cloth hookup cable and vintage-style "keyed" bottom plate.
Bridge and neck postions are regular. Middle position is reverse wound, reverse polarity (RW/RP) for hum-cancelling in positions '2' and '4' on a Strat 5-way switch.
