Description

Behold the Seymour Duncan JB Jr. SJBJ-1, a unique, twin-coil design pickup that packs the power of a full-size humbucker into a single-coil size. This marvel of a musical accessory offers an exceptional balance of great harmonics and a sweet high-end, designed to cater to a range of music styles, from heavy blues to heavy metal.

Unlike most humbuckers, the JB Jr. SJBJ-1 features adjustable pole pieces, giving you the freedom to fine-tune the balance of your strings and effectively emulate the magnetic field of a full-size humbucker - a first for a humbucker this size. With a high output and enhanced high-end response, this pickup not only adds depth and dimension to your music but also provides a tonal character that works well with both maple and rosewood fingerboards.

An added bonus? The Seymour Duncan JB Jr. SJBJ-1 requires no modification to your instrument, allowing Strat players to reap the benefits of a high-output humbucker without any hassle. The pickup comes with a four-conductor hookup cable to facilitate complex switching options, ensuring you get the most out of your music-making experience.

Critic Reviews

SJBJ-1 JB Jr Review: The day I got this put in I was so happy... | Seymour Duncan | Pickups | Reviews @ Ultimate-Guitar.Com

ultimate-guitar.com

The Seymour Duncan SJBJ-1 JB Jr. shines as a compact yet powerful pickup, delivering the punch of a full-size humbucker in a single-coil format. Ideal for high-gain styles, it offers clarity and separation even at high distortion levels, making it a favorite for genres like Nirvana-style grunge.

The review is overwhelmingly positive, praising its reliability and transformative impact on the reviewer’s guitar setup.

Nice

I use mine in the bridge position of my Strat. It's not good for clean sounds. For overdriven tones it's amazing!
