Until now, if you wanted humbucker, P-90, and vintage Strat tones, you'd have to haul three guitars to the gig. But that was before the Seymour Duncan SHPR-1 P-Rails pickups. P-Rails feature a ground breaking, patent pending design allows a full-size humbucker to split to either a real deal P-90 or a traditional single-coil. Perfect for a wide variety of styles including country, pop, surf, jazz, blues, classic rock, and heavy rock.The humbucker sound is full and expansive, owing to the mis-matched coil configuration. The P-90 is a super fat. And the Rail coils, when used together, sound like the 2 and 4 "in-between" positions in a great Strat.P-Rails can be used in any guitar set up for a traditional humbucker or Trembucker. A single P-Rails will bring added dimension to your guitar sound. However, to optimize the unique splitting capabilities and get the best single-coil Rails tones, use a neck and bridge set.To get both humbucker and P-90 tones, use a two-way switch (push-pull or mini-toggle). To have humbucker and P-90 tones and bring in the added dimension of the single-coil Rail guitar pickup, use a three-way switch (DPDT on-off-on).
