NS-Design NXT4a Upright Bass 4-String (satin sunburst)

NXTa Upright, whose electronics are fully based around the Polar™ Pickup System, share the classic body design, ergonomics and performance support options of the CR and EU Series. Available in 4 and 5 string configurations, these instruments are produced in the Czech Republic by the same craftsmen who build NS Design’s most advanced instruments.


DUAL MODE OUTPUT – The new dual mode signal output electronics of the NXTa take the convenience, versatility and performance capability of the NXT to another level.

ACTIVE MODE – Using the supplied charger, the NXTa connects into any AC outlet for 60 seconds, powering the capacitor-powered active circuit for 16 hours from the time of the charge. The instrument can then be plugged straight into any low or high impedance device, 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 – The NXTa can be played in this mode when using a direct box or an amplifier with high impedance input. (This mode provides performance capabilities identical to the original NXT.)

ECO-FRIENDLY OPERATION – NXTa instruments are battery-free, eliminating the hassle and cost of batteries while helping protect our environment.

SOLID MAPLE BODY AND NECK – together with the graduated fingerboard, deliver a rich, full tone that rings true for every note. Asymmetrical fingerboard relief facilitates an even ‘growl’ from the higher strings and a clear, powerful lower register. The adjustable bridge and truss rod allow for low, fast action, or for higher string settings that encourage the traditional acoustic player to ‘dig in’ with gusto.

NS ELECTRIC STRINGS and most traditional acoustic strings fit all NS Double Basses, allowing the player to select from a wide range, each with a unique sound and feel. In combination with the easy adjustment of basic set-up parameters, the NXTa Series Bass is adaptable to many different styles of music.

GIG BAG AND FLIGHT CASE – The NXTa double bass includes a padded gig bag that has a pouch for tripod stand, a bow compartment and room for the charger and accessories. The loaded gig bag will fit in the overhead compartment of most commercial aircraft. An optional hard-shell flight case is available for the NXTa double bass.
