Seymour created this classic humbucker combination while in England in 1974, and it remains his favorite set of pickups to this day an SH-4 JB for the bridge and SH-2n Jazz Model for the neck. Together they provide one of the most versatile humbucker ever built. The JB Model humbucker is our most popular pickup of all time. It adds juice and versatility to the bridge position of any humbucker equipped guitar. With its hot coils, and alnico 5 bar magnet, this pickup delivers an unmistakable upper midrange attack, a tight, articulate low end, and harmonically rich highs that can really sing. The JB is the perfect bridge pickup for anything from blues & country to the meanest hard rock & metal. The Jazz Model neck humbucker uses an alnico 5 bar magnet and a special coil wind for an articulate, glassy treble response that balances very well with its full, but tight low end. The scooped midrange gives this pickup a smooth tonal character all its own. Originally designed as the matching neck pickup for the JB Model bridge pickup, the Jazz is an incredibly versatile humbucker that will work for almost any style of music. The Jazz Model is an excellent neck position counterpart for almost any of our moderate to high-output bridge humbuckers. The Jazz Model has been used by many great players over the decades, from Randy Rhoads to Jeff Beck to Seymour W Duncan. Hand built in our Santa Barbara, CA, factory, these humbuckers use an alnico 5 bar magnet, nickel silver bottom plate, 4-conductor lead wire for multiple wiring options, and are vacuum wax potted for squeal-free performance.
