Woodbrass JB100 Black

A JB100 Inspired by "J-type" Standards

The Woodbrass JB100 follows the lineage of J-type format basses, appreciated for their ergonomics and adaptability across many genres. With a solid body construction, a proven pickup configuration, and straightforward passive controls, it focuses on the essentials: an accessible, coherent bass ready to support the bassist's development.

Who Is This Bass For and Which Styles?

The JB100 is particularly suited for beginner to intermediate bassists seeking a stable instrument that is easy to set up and expressive enough to grow with. Its two J-style pickups feel at home in rock, pop, funk, jazz, or reggae: neck pickup for a rounder tone, bridge pickup for more attack and definition, or both for a versatile balance.

The Sound

The 2 J-style pickups provide precise articulation: present lows, defined mids, and highs that can "snap" when the tone control is opened. The passive electronics (2 volumes + 1 tone) favor a natural and dynamic sound, highly responsive to right-hand intensity and blending between pickups. The basswood body promotes a balanced output that sits well in a mix, while the maple neck adds attack. The rosewood fingerboard slightly rounds off the high end for a comfortable tone appreciated in both fingerstyle and pick playing. The traditional 4-saddle top-load bridge contributes to a clear attack and makes string changes easier.

Recommended Compatible Accessories

To maintain the original feel, choose a set of 4-string long scale bass strings (34" / 864 mm scale) with a 45-100 gauge, identical to the factory setup. A standard strap will also improve comfort when playing standing up.
