Ned Steinberger’s approach to the Radius series - as with every new instrument - has been to re-explore each facet of a bass guitar, leading to innovations that provide the player with amazing physical comfort, exceptional performance and unparalleled versatility. The new NXTa brings together brilliant ergonomics of the headless neck and body configuration, the NS self-clamping tuning system, custom NS/EMG™ pickups, volume-volume-tone controls, and battery-free Dual Mode Output electronics made for NS by Mi-Si™.

"The NXTa Radius is an innovative and engineering work of art, beauty, and tone to perfection." — Ty Campbell, Bass Musician Magazine

Available fretted or fretless, in 4 or 5 string configurations, the NXTa Radius Bass Guitar is beautifully crafted in the Czech Republic from solid, straight grain maple, with a maple face (Satin Black model) or flame maple face (Sunburst model).

NS Radius Neck

The headless, one-piece, bolt-on maple neck has 24 frets, a 34" scale and a familiar 15" radius. A volute provides thumb reference at the nut. String slots in the aluminum headplate eliminate the need for a headstock with heavy tuning machines. Conveniently accessed from the top of the neck, the heavy-duty aluminium double-action reinforcing truss rod, with its patented differential thread drive, gives both rigidity and precise relief control.

NS Diradial™ Body

The concave back profile provides a sense of comfort and stability against the torso. The front of the instrument is more tightly radiused, which, in combination with the general wedge shape of the body, creates a more comfortable orientation to the right hand. The configuration of the body cutaway provides easy access to the highest frets.

NS Patented Tuning System

Fast and simple, this self-clamping precision tuning system (US Patent #6,528,710) is integrated into the body of the Radius Bass. Any standard single-ball end, full-scale bass guitar string can be used. No tools are needed: simply rotate the knurled knob to change a string or tune the instrument.

NS/EMG™ Pickups

The NS/EMG Radius features custom magnetic pickups with a radiused top and magnetic structure designed to optimally capture the full richness of tone from every string. The controls are a familiar Volume-Volume-Tone configuration. The Tone control is also a push-pull knob, used to select between the NXTa’s active or passive output modes.

Dual Mode Active/Passive Electronics

All NXTa series instruments feature battery-free, high performance active electronics with new capacitor-powered custom circuitry designed  by Mi-Si™ Electronics Design.

Active Mode
In Active mode, the user connects the supplied charger into an AC outlet for 60 seconds to power the circuit for up to 16 hours of performance time. The instrument can then plug straight into any amp, low or high impedance, no direct box necessary. Since there is no signal loss over the full frequency spectrum of the instrument, the fundamentals of every note remain clear and strong, even with extra-long cables.

Passive Mode
In Passive mode, NXTa models can be used with an amplifier with a high impedance input, or with any amplifier using a direct box.

Eco-Friendly Operation
NXTa instruments are battery-free, eliminating the hassle and cost of batteries while helping protect our environment.

NS Bridge & Saddle

The aluminium one-piece bridge and saddle assembly provide a broad range of height and angle adjustment, allowing the player to precisely tailor the action and adjust the intonation.

NS Gig Bag

The WAV Radius bass guitar includes a padded gig bag with a handle, adjustable backpack straps and a large front zipper pocket with room for cables and gear. The loaded gig bag will fit in the overhead compartment of most commercial aircraft.
