Seymour Duncan 11303-03-B SHPR-1S Set of P-Rails Versatile Humbucker Electric Guitar Pickups

SKU:  ae00-1453
Manufacturer Part #:  11303-03-B
Seymour Duncan SHPR-1s, Full-Size Humbucker Splits to a Full-Size P-90 or Special Alnico Single-Coil Rail Pickup P-Rails Set Black


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.


Until now, if you wanted humbucker, P-90, and vintage Strat® tones, you’d have to haul three guitars to the gig. Enter P-Rails™. It’s a full-size humbucker that splits to either a full-size P-90 or a special Alnico-powered single-coil Rail pickup. 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” positions in a great Strat.

Complete Setup 

P-Rails are best used in a matched 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, use a three-way switch (DPDT on-off-on).


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. However, to optimize P-Rails’ unique splitting capabilities and get the best single-coil Rails tones, use a neck and bridge set.

Available Mods 

Normally, in humbucking mode, P-Rails are wired in series, for a high-output sound that works great for classic rock and heavier tones. However, when wired in parallel, the coil mismatch produces a very usable P.A.F.-style humbucker tone with less phase cancellation associated with standard parallel wired humbuckers, complete with present upper-mid “bloom” and pronounced string articulation.
