The NXTa Double Bass opens up a new horizon for the serious bassist looking to play a great instrument on a limited budget

Available in 4 and 5 string configurations, these instruments are produced in the Czech Republic by the same craftsmen who build NS Design's renowned EU and CR Series instruments and exemplify world-class design and flawless craftsmanship at a more affordable price point. With a visual appearance as striking as its sound, the roadworthy NXTa design is an exciting and reliable partner for the most demanding performance career.

Sporting a full double bass scale length, the NXTa Double Bass features a solid maple body and neck with a graduated ebony fingerboard for 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 Polar Bridge Pickup System

Pizzicato and arco techniques have almost unlimited expressive potential, thanks to the NS Design Polar™ Pickup System...  Two separate mounted transducers beneath the bridge offer unlimited expressive potential and powerful dynamics. With each pickup specialized for a specific task, a convenient switch gives you the choice to select a traditional arco mode for percussive attack and a dynamic bowed response, or the pizzicato mode for a smooth, sustained tone.

Dual Mode Output

New NS Design dual mode signal output electronics take the convenience, versatility and performance capability of the NXTa 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 up to 16 hours of performance time. 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.

NS Design/D'Addario™ Strings

Equipped with NS Contemporary Bass Strings by D'Addario™, the NXTa is compatible with most standard electric or traditional acoustic upright bass strings. In combination with the easy adjustment of its basic set-up parameters, this versatile instrument is adaptable to many different styles of music.


Includes a self-supporting tripod stand with full adjustments for height and angle plus a nylon padded gig bag with stand compartment, bow compartment, charger and accessory pocket, handle and adjustable shoulder strap. With a loaded weight of 11.2kg (25lbs) including stand, the NXTa Double Bass fits in the overhead luggage compartment of most commercial aircraft.

A fabulous bass
13 June 2012  | 

A fabulous bass. I have been gigging every week for over two years with this bass and it always receives complementary comments for its sound and looks. The supplied gig bag and stand were not of very good quality... the original gig bag split after one week's use, so The Bass Centre sent a replacement gig bag free of charge, which was of far superior quality. The top of the original stand sheared off recently so I decided to upgrade to the more expensive stand, which is standard equipment for the CR bass. The Bass Centre gave me a good deal on the new stand. The NXT is a great bass so maybe think about upgrading to the superior stand when purchasing.

Even better than expected

This is a wonderful instrument with fantastic sounds. It has taken a little time to get used to it but as my technique improves,so the results get better and better, and I'm sure will continue to reward for many years to come. The instrument is beautifully made and it's a pity that the same couldn't be said about the tripod stand. The one that arrived with mine was flimsy and damaged. However, following a phone call to the Bass Centre, a new, more substantial one arrived within two days. Excellent service to complement an excellent product. Despite the stand, I still rate the bass with five stars and thoroughly recommend it as representing excellent value for money.
