Description
Some pickups make you choose a lane. The SHPR-2b P-Rails Hot refuses to. Drop it into the bridge and you get three genuinely different personalities from one humbucker-sized unit: a thick, saturated humbucker, a snarling P-90, and a bright, articulate single-coil voice reminiscent of a Strat. It’s built for players who don’t want to compromise between vintage character and modern drive.
The “Hot” designation isn’t just marketing — this version carries a beefed-up coil wind paired with dual Alnico 8 magnets, which push output closer to ceramic territory while keeping the singing sustain Alnico is loved for. The P-90 side uses a specially selected wire for extra clarity at high output, so it stays articulate even when driven hard. Split into single-coil rail mode and that Alnico 8 muscle keeps things surprisingly hot for a coil-split tone, while full series humbucker mode is downright massive.
Since it’s built to standard humbucker/Trembucker dimensions, this is a straightforward retrofit into any guitar routed for a traditional humbucker. For full access to all three voices, Seymour Duncan suggests pairing it with a standard P-Rails in the neck (sold separately), switched via a push-pull or mini-toggle for humbucker/P-90 selection, plus a DPDT on-off-on switch to unlock the single-coil rail tones — or simplify everything with a Triple Shot switching ring (sold separately).
- Series wiring delivers high-output humbucker tone for rock and heavier styles
- Parallel wiring gives a lower-output humbucker sound with reduced phase cancellation versus standard parallel humbuckers
Versatile enough for any genre, and hand-built in Santa Barbara, California.
