Seymour Duncan SJBJ-1b JB Jr Strat Parchment Pickup

The SJBJ-1b JB Jr is a high-output single-coil-sized humbucker engineered for bridge position installation in Strat-style guitars. This pickup delivers aggressive, articulate tone in a compact form factor that fits standard single-coil cavities without routing, making it an ideal choice for players seeking humbucker aggression without sacrificing their instrument's original body dimensions.

Tone & Output Character

Built with a twin coil design and ceramic magnets, the JB Jr produces the thick, punchy midrange and sustain characteristic of Seymour Duncan's JB lineage. The 15.2 kOhm DC resistance yields high output suitable for rock, metal, and hard-hitting blues applications while maintaining clarity and definition across the frequency spectrum.

Construction & Reliability

This pickup is wax potted for microphonic feedback elimination and long-term stability. The adjustable pole pieces allow fine-tuning of magnetic balance and output across individual strings, while the included four-conductor hookup cable enables flexible wiring options for coil-splitting and series/parallel switching.
