NS Design NXT4a Electric Upright Bass, Black

Battery-free electric upright bass with rich tone and versatile performance support

The NS Design NXTa Electric Upright Bass is a modern electric upright bass built for players who want the feel of an upright instrument with the flexibility of a stage-ready amplified setup. Designed for jazz, orchestral crossover, studio work, and contemporary performance, the NXTa offers a streamlined profile that travels more easily than a traditional acoustic bass while still delivering a full, resonant voice. Its solid maple construction and carefully graduated fingerboard help produce a focused, expressive sound with strong articulation across the range.

A key advantage of the NXTa is its battery-free dual-mode electronics, giving bassists dependable performance with both active and passive output options. The Polar directional piezo pickup system is designed to respond differently for arco and pizzicato playing, making this an appealing choice for musicians who switch between bowed passages and plucked lines. With included tripod support and compatibility with additional support systems, the NXTa is especially well suited to players seeking a professional electric upright bass for rehearsal, performance, and travel.
