TB-4 JB Trembucker for Bridge Position (4 Conductor) SH-2 Jazz Humbucker for Neck Position (4 Conductor) The ultimate Hot Rodded humbucker pickups, the JB (SH-4) and Jazz Models (SH-2) make for a versatile combination that will breathe life into any guitar. SH-4 JB for the bridge and SH-2n Jazz Model for the neck. Together these pickups have become one of the most timeless and versatile humbucker sets ever built. 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 and 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 harmonics. Use it with a 500k volume pot for great high-end cut, or try a 250k pot to sweeten and soften the tone for smoother styles.It pairs particularly well with the Jazz or'59 neck pickups, and some players even like to use a JB in the neck position for an extra-fat solo tone. 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 Jazz Model has been used by many great players over the decades.
