Seymour Duncan

JB Model SH-4

Hot-rodded bridge humbucker; Duncan's most popular model

Humbucker

The JB Model is Seymour Duncan's most popular pickup. Official copy describes a full, powerful low end, crisp detailed highs, and an upper-midrange bump that adds crunch to chords and a singing quality to single notes, with hot output that pushes an amp harder for sustain and harmonics. The maker lists blues, country, fusion, punk, hard rock, grunge and thrash as styles it has been used in, and recommends pairing with a Jazz or '59 neck pickup.
