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.

Key Features

  • JB Model tone with modern rail humbucker design
  • Tight lows, strong highs, and signature upper midrange bite
  • Rail-style construction for improved string balance and sustain
  • Alnico 8 magnet for high-gain clarity and punch
  • 4-conductor lead wire for multiple wiring options
  • Available in 6-string and 7-string versions

If you’re looking for the classic JB sound with modern performance enhancements, the Seymour Duncan JB Rails is your ultimate pickup upgrade.
