The Seymour Duncan JB Rails reimagines the legendary JB Model in a sleek rail humbucker design, delivering classic high-output tone with enhanced clarity and balance. Whether you're diving into high-gain leads, tight rhythm work, or expressive soloing, this pickup brings the perfect mix of power, sustain, and articulation for modern players.
JB Power with Enhanced String Balance
By fusing the classic JB tone—with its tight low-end, strong highs, and upper midrange bump—into a rail-style pickup, the JB Rails ensures even magnetic distribution across the strings. The result is improved string balance, increased clarity, and extended sustain, making it ideal for everything from searing solos to articulate rhythm work.
Optimized for High-Gain Applications
With an Alnico 8 bar magnet, the JB Rails takes the classic JB punch and adds extra aggression and articulation, making it a perfect choice for high-gain tones. It retains the singing lead tones and full-bodied crunch that have made the JB Model an industry standard.
Wiring Versatility & Potentiometer Tweaks
A 500k volume pot accentuates high-end bite and presence.
A 250k volume pot smooths out the tone for a warmer, rounder sound.
4-conductor lead wire allows for series, parallel, or split-coil wiring, providing a range of tonal options.
Handcrafted Quality & Multi-String Compatibility
Each JB Rails pickup is hand-built in Seymour Duncan’s Santa Barbara, CA factory, wax-potted for squeal-free performance, and available in 6-string and 7-string versions. It pairs perfectly with the Jazz Rails neck pickup for a balanced, versatile setup.

Rail-style construction for improved string balance and sustain
Alnico 8 magnet for high-gain clarity and punch
