Seymour Duncan SJBJ-1n JB Jr. for Strat Black Pickup

The JB Jr. brings the aggressive, articulate character of Seymour Duncan's classic JB humbucker into a single-coil form factor that drops directly into any Strat pickup cavity. Built for neck or middle position, this pickup delivers full humbucker output and tonal authority while fitting existing single-coil routes—no routing required. It's the upgrade path for gigging players who need high-output punch and stage reliability without modification work.

Tone & Output

A ceramic magnet and 10.1k ohms DCR deliver hot, defined output with crisp treble response and muscular midrange—characteristic of the JB lineage. The twin coil design maintains full humbucker complexity while the hum-cancelling construction eliminates 60-cycle noise, keeping your signal clean under stage lights and during high-gain passages.

Design & Build

Hand-built in Santa Barbara, California, this pickup features adjustable pole pieces for fine-tuning string balance and voicing to your touch and playing dynamics. The wax potted construction prevents microphonic feedback during live performance, while a four conductor shielded cable ensures clean signal transmission and maximum flexibility for series/parallel wiring configurations.
