Description

The Seymour Duncan SH-4 JB Rails Bridge Humbucker Pickup is the perfect fusion of classic rock tone and modern innovation. Designed for musicians who crave the iconic punch of the JB Model but with a twist, this pickup delivers powerful, clear tones with exceptional sustain.

What sets the SH-4 JB Rails apart is its rail technology, which ensures that each string is treated to a consistent magnetic field, thanks to its Alnico VIII bar magnet. This results in an even string response and a tight, controlled sound. Whether you're ripping through high-gain solos or laying down bluesy riffs, the JB Rails excels with its punchy low end, crisp highs, and pronounced upper mids.

Handcrafted in Santa Barbara, California, this pickup is meticulously built with vacuum wax potting to eliminate unwanted squeals, making it reliable even at high volumes. The 4-conductor lead wire offers versatile wiring options, allowing you to tailor your sound through series, parallel, or split-coil configurations. Pair it with a 500k volume pot for enhanced top-end definition or a 250k pot for a slightly warmer tone. Ideal for both 6-string and 7-string guitars, the SH-4 JB Rails is a robust choice for any musician aiming to enhance their sound with clarity and articulation.

Key Features:

  • Iconic JB Model tone with modern rail design
  • Alnico VIII bar magnet for balanced string response
  • Vacuum wax-potted 4-conductor lead wire
  • Versatile wiring options: series, parallel, and split-coil
  • Handcrafted in Santa Barbara, California
