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 captures 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 ideal for home studios and session work where tonal flexibility matters without hardware modification.

Tonal Range & Recording Character

Three switchable modes give you complete control in the mix: the Humbucking mode peaks at 3.0kHz for full, balanced output with 18.80kΩ resistance, translating to solid body weight in dense arrangements; P-90 mode emphasizes midrange at 3.1kHz with 10.20kΩ resistance for that classic jangle that cuts through without muddiness; and Rails mode delivers a tight, aggressive attack peaking at 6.0kHz with 8.56kΩ resistance for slicing lead passages or rhythm texture. The three distinct resonant peaks let you tailor your tone across your entire production palette—from rhythm layers to lead takes.

Design & Studio Reliability

Vacuum wax potting eliminates microphonic squeal and feedback, ensuring clean, stable operation during tracking sessions and at any monitoring level. 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 for quick mid-session tone changes.
