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.

An excellent bass, recommended

Rapid delivery, allbeit done in a somewhat cavalier manner by UPS. The bass is superb, the set up was good, the sounds are amazing! The strings are reminiscent of Thomastik Superflexibles. Will just have to get used to the extra B string, a work in progress.

Thank you Barry and The Bass Centre.

A Very Good & Beautiful Instrument
14 February 2015  | 

Hello from France, and again, please excuse my bad English!

I bought this NS design NXT-5 (five strings). A very beautiful and well done electric upright bass.
The build quality is excellent!

I don't have to do any more settings, probably already check, the neck is very good like the action of the strings (perfect adjustment for me), very easy to play. I'm very suprised by the play-ability.... just plug and play

The included soft cover (gig bag) and tripod stand is good too, very practical and solid. In my opinion, the NS Contemporary strings (which are light gauge) seems a bit too "electric bass-sounding" for me, and need to be replaced with traditional strings for more "upright sounding".

So a very good value for the price. I love it

I'm also really really pleased by the seriousness of The Bass Centre. Thank you guys, a pleasure to deal with you. I bought the NXT-5 on a Sunday on the internet site and I recieved it, at home in France, on the Wednesday !!! super fast and well packed !!!!

Bye and, again, thanks to the team of Bass Centre.
