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

The JB Jr. delivers the aggressive, articulate character of Seymour Duncan's classic JB humbucker compressed into a single-coil form factor that drops directly into any Strat pickup cavity. This neck or middle position pickup combines full humbucker output and tonal authority with the ergonomic advantage of fitting existing single-coil routes, making it an efficient upgrade path for players seeking high-output punch without routing 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, making this pickup suitable for high-gain applications and studio recording.

Design & Build

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