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: the Humbucking mode peaks at 3.0kHz for full, balanced output with 18.80kΩ resistance; P-90 mode emphasizes midrange at 3.1kHz with 10.20kΩ resistance for that classic jangle; and Rails mode delivers a tight, aggressive attack peaking at 6.0kHz with 8.56kΩ resistance for cutting leads. The three distinct resonant peaks let you tailor your tone across a working guitarist's entire playing range.

Design & Build Quality

Vacuum wax potting eliminates microphonic squeal and feedback, ensuring clean, stable operation at any volume. 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.
