Seymour Duncan TBPR-1b P-Rails Original Trembucker Bridge Pickup

The TBPR-1b P-Rails is a workhorse bridge pickup that gives you three complete voices from one unit—full humbucker bite, vintage P-90 warmth, and articulate single-coil rail clarity—all switchable on the fly via mini-switch. Built with trembucker spacing for guitars with wider string spacing, it locks in tight across all configurations, delivering the clarity and punch you need for live performance without sacrificing tonal range.

Design & Construction

Alnico 5 bar magnets and vacuum wax potted construction deliver the tonal character and reliability Seymour Duncan is known for, with each unit hand-built in Santa Barbara, CA. The trembucker's 2.070" pole spacing is engineered specifically for bridge positions on instruments with string spacing greater than 2 inches, ensuring proper alignment and optimal magnetic field interaction across all six strings.

Tone & Configuration

The P-Rails technology unlocks three distinct voice palettes—traditional humbucker, vintage P-90, and articulate single-coil rail—all accessible through a standard 3-way (on-off-on) mini-switch. The 4-conductor lead wire enables full wiring flexibility, letting you dial in anything from thick and aggressive bridge tones to clean, articulate textures that cut through a live mix without getting muddy.
