No One Does Tone Like Seymour Duncan!
Seymour Duncan's JB Jr. SJBJ-1 packages the tone of Duncan's hugely successful JB humbucker into a single-coil-sized pickup. The polepieces are totally adjustable, allowing it to more closely emulate the magnetic field of a full-size humbucker plus controlling the string-to-string balance. While not as hot as Duncan's Hot Rails, the high-end response has been enhanced on the JB Jr. SJBJ-1. Strat players - with no modification to the instrument - can reap the benefits of a high-output humbucker with the JB Jr. SJBJ-1.Seymour Duncan JB Jr. SJBJ-1 at a Glance:

The JB Jr. SJBJ-1 high out single-coil-size "rails" humbucker is killer for everything from heavy blues to heavy metal. The twin-coil design features the character of our popular JB model humbucker in a single-coil size. Its fully tweakable pole pieces more closely emulate the magnetic field of a full size humbucker and allow you to fine tune the balance of your strings. You can expect killer harmonics and a sweet high-end. Compared to Hot Rails, the output is reduced and there's more treble response, and the JB Jr. SJBJ-1 comes with four-conductor hookup cable to facilitate complex switching options.
