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.
