Seymour Duncan SHPR-1b P-Rails Bridge Black Pickup

Seymour Duncan SHPR-1b P-Rails Bridge Black Pickup

The SHPR-1b P-Rails is a versatile bridge humbucker that delivers three distinct voicings from a single pickup, letting you dial in anything from thick, articulate humbucking tones to bright, snappy single-coil character without rewiring. This drop-in replacement fits any standard humbucker cavity, making it an ideal choice for players seeking tonal flexibility without modification.

Tonal Range & Performance

Three switchable modes give you complete control on stage: the Humbucking mode peaks at 3.0kHz for full, balanced output with 18.80kΩ resistance, sitting thick and commanding in the mix; P-90 mode emphasizes midrange at 3.1kHz with 10.20kΩ resistance for that classic jangle that cuts through live; and Rails mode delivers a tight, aggressive attack peaking at 6.0kHz with 8.56kΩ resistance for cutting leads that punch through. The three distinct resonant peaks let you tailor your tone across your entire playing range without breaking stride during a set.

Design & Build Quality

Vacuum wax potting eliminates microphonic squeal and feedback, ensuring clean, stable operation at any volume—critical for consistent performance night after night. The pickup uses two Alnico 5 bar magnets for dynamic response and sustain, paired with a standard 4-conductor leadwire that supports full switching flexibility.
