Seymour Duncan SH-4 JB Rail Pickup, Black

The JB humbucker, arguably Seymour Duncan’s most famous pickup, gets an impressive rail-designed revamp in the form of the SH-4 JB Rails. Packing in the original JB’s fantastic top- and bottom-end power with its boosted upper midrange, the SH-4 JB Rails is already off to a hot start. Then factor in a beautifully balanced rail design that showcases each string across an Alnico VIII bar magnet to perfectly account for all frequencies, and you’ve got a smoking hot recipe for delivering clear, even, and articulate tones with excellent sustain. It makes a perfect match for Seymour Duncan’s Jazz Rails neck pickup. You’ll notice a corresponding boost in top-end definition or a slightly mellower tone when paired with either a 500k or a 250k volume pot, respectively. Carefully handbuilt at Seymour Duncan’s factory in Santa Barbara, California, the meticulous internals of the SH-4 JB Rails feature vacuum wax-potted 4-conductor lead wire designed to minimize pesky squeal and offer wiring options for series, parallel, and split-coil applications. The SH-4 JB Rails is available in both 6-string and 7-string models.
