The JB Model humbucker is the most popular pickup Seymour Duncan makes. Blues, country, fusion, punk, hard rock, grunge, thrash; the JB has always sounded just right, even as new genres emerged around it. The low end is full and powerful, the highs are crisp and detailed. There’s an upper-midrange bump that adds crunch and chunk to heavy chords but translates to a singing, vocal-like quality when you play single notes or solos. Meanwhile the hot output pushes your amp just that little bit harder for more sustain and richer harmonics.
