Seymour Duncan SJBJ-1b JB Jr. for Strat White Pickup

Seymour Duncan SJBJ-1b JB Jr. for Strat White Pickup

The Seymour Duncan JB Jr. packs aggressive, punchy output into a single-coil-sized format that drops straight into your Strat bridge without routing. This high-output rails design delivers humbucker-level intensity while preserving clarity and articulation—no compromise on cut or definition across the frequency spectrum.

Tone & Output Character

Built with a DC resistance of 16.09 kΩ and resonant peak at 3.6 kHz, the JB Jr. sits right in the midrange punch zone, cutting through a live mix with authority. The ceramic magnet and adjustable pole pieces let you dial in responsive dynamics and fine-tune the response to your playing, while the EQ curve of 4/6/5 (Bass/Midrange/Treble) keeps things forward and aggressive—perfect for rock, metal, and high-gain tones on stage.

Construction & Wiring

The twin coil design with hum-cancelling technology kills 60-cycle hum without losing tonal character in the bridge position. Wax potting keeps everything stable and road-ready, while the 4-conductor lead wire opens up series, parallel, and split wiring options for expanded sonic flexibility.
