FOR THE BASSIST ENTERING THE WORLD OF THE PURE ELECTRIC UPRIGHT the NS Design WAV Series offers a combination of design, performance and affordability exceeding any other instrument in its price point. True to the NS tradition, the WAV readily captures the essence of an acoustic double bass, yet opens up a wide range of new sonic possibilities.

The piezo-powered, passive electronics deliver an amazingly natural tone with unlimited overhead for extraordinary performance without the need or hassle of batteries whilst the NS patented Polar™ Pickup System offers the modern bassist unlimited expressive potential and a range of powerful dynamics.

The WAV upright bass is available in 4 or 5 string models with a choice of stunning color choices. 

Construction & Design

The WAV Series proudly shares the same elegant, modern body design, ergonomics and performance support options of its NXT and CR companions and delivers the same rich, full tone and clarity you would expect from a Ned Steinberger Instrument.

The WAV Double Bass features a solid straight grain maple neck and body with a gorgeous flame maple face (with a choice of Amberburst, Transparent Red and Transparent Black stained finishes) or a striking Brilliant White solid maple face. The graduated rosewood fingerboard features asymmetric relief for easy playability in every position whilst the adjustable bridge and two-way truss rod allow the player to radically adjust the neck relief and string heights to suit the music and personal playing style.

NS Polar Bridge Pickup System

Pizzicato and arco techniques have almost unlimited expressive potential, thanks to the NS Design Polar™ Pickup System. Two separate piezo transducers mounted in the bridge respond selectively to either vertical vibration - a convenient toggle 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, uniquely even and sustained plucked sound.

NS Design/D'Addario™ Strings

Equipped with NS Contemporary Bass Strings by D'Addario™, the WAV Double Bass 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 suit all styles of music.


Compact and lightweight, the WAV Double Bass is an excellent instrument for musicians on the move. It comes equipped with a self-supporting WAV/NXT tripod stand with full adjustments for height and angle and a padded gig bag with a carry handle, adjustable shoulder strap and separate pouch compartments for stand, bow and accessories. The gig bag with a loaded weight of approximately 11.2kg/25lbs (including stand) will fit in the overhead compartment of most commercial aircraft.

Polar Pickup System

As a player, you may not think about the direction your strings are vibrating, or even be aware that string vibrations on a musical instrument are polarised in relation to the fingerboard and the motion of the plectrum and bow. Yet direction is one of the most significant factors influencing the tone and response of a stringed instrument. In fact, instruments from the violin family are different from the lute or guitar in large part due to the effects of string polarisation.

The bow drives the string back and forth in the direction of the bow, while at the same time it suppresses the up and down vibration. You can see this effect with the naked eye by watching the wide excursion of the lowest strings when bowed. From the front, you can see a wide lateral pattern of string vibration, but looking from the side you can see almost no pattern at all. Instruments in the violin family have a tall bridge in combination with an asymmetrical support structure of bass bar and sound post that efficiently translate the sideways motion of the bowed string into sound.

The Polar pickup responds with a high degree of lateral sensitivity and vertical rejection that is tailored to mirror the polarity of the bowed string. The result is a remarkably dynamic, rich tone that responds effortlessly to the bow.

The Polar pickup takes this concept one step further, and is able to switch from lateral to vertical sensitivity, which is ideal for pizzicato. Unlike the violin, a flattop guitar or lute respond in the vertical direction, to minimise the plucked attack and store energy for longer sustain. With the touch of a finger, the polar pickup can switch from lateral to vertical mode. In the vertical mode the attack is controlled for a sustained, singing pizzicato response. The lateral mode has the opposite effect, and the plucked response is extraordinarily percussive, like a traditional bowed instrument, only more so. This dual capacity allows the player to control attack and decay, adding new expressive potential to the violin family of instruments.


The fully adjustable mono-pod design allows the player to set the instrument in a position like that of an acoustic double bass. The point where the end pin touches the floor can be easily adjusted so that the weight of the instrument is centred over the tip. This balances the instrument, leaving both hands free for expressive play.

Boomerang STRAP

The Boomerang Strap System gives the player full mobility, and the freedom to play in virtually any position without stress and fatigue. The simple design incorporates two support arms and a pivoting friction hub that holds the instrument firmly in place, yet allows the instrument to be moved into virtually any position in relation to the hands and body as it is played.

The secret of the Boomerang Strap is that the instrument can be rotated into place without moving the strap itself. With the strap over the shoulder like a guitar, the arms adjust to a comfortable position against waist and hips. The player can now move the instrument into the ideal playing position without changing the position of the strap; vertical, horizontal, or anywhere in between, with the fingerboard and strings tilting in toward the body or away, the strap system still remains in place, firm and comfortable against the body. The result is freedom of expression with unprecedented comfort for bow and pizzicato styles of play.

The Boomerang system fits all models of the Omni Bass, NS Double Bass, and NS Cello. The strap system screws into the same mounting insert that is used to for the & Stands so that all three support systems are easily interchanged.

Frame Strap

Lightweight frame design has triangulated body contact points to provide a high degree of stability and comfort.

Convenient height and angle adjustments allow players to accommodate personal styles of play. In addition to the vertical position, the neck can be angled horizontally like a guitar for picking and strumming.

A single wing nut secures the instrument in place for fast set-up and breakdown. The strap system fits both cello and double bass.

Virtually all traditional playing techniques are possible, including thumb position. The instrument neck is tilted back and close to the shoulder, but the body angles out, away from the body for excellent bow access across the full arc of play. This angle also helps traditional cello and bass pizzicato technique to sound and feel natural.

Hi Mark,

 Sorry for the delay! Hope you are well. Just e-mailing you to thank-you for getting the NS NXT bass out to me! It is probably the best Instrument I have ever brought for less than £1000. When it comes out of the box its a little disappointing for someone looklng to nail the upright bass tone. However, after changing the strings for the traditional set and raising the bridge the difference is huge. The other unforeseen benefit is it looks so great my partner does not mind seeing it around the house, she thinks it looks like an expensive ornament. So I am not always being told to put the bass away!

Many Thanks

Hi Mark

Just a quick note of thanks for your help in choosing the NXT5 upright and EBS amp on Monday. I'm very pleased I went for the five string. It all sounds great including/especially when through a PA.

I will at some point soon I will want to choose a footswitch/pedal to be able to select either the NXT or my BG (active with piezo pick up). The signals are of course very different. Can you suggest any budget options?



Submitted on the 24th April 2010 by Paul who purchased the NS Design, NXT 5 string EUB


Just wanted to say thanks for the great service in getting me the NXT 5 string.  The bass arrived as promised on Thursday in A1 condition.  Having had a chance to play it over the last week, it really is a great instrument.  Very well finished and a great natural tone.  The amplified bowed and pizzicato sounds are excellent.  I'm still getting familiar with the instrument and having been playing double bass for over 25 years its amazing how reliant you are on the physical features of the double bass for intonation and navigation around the fingerboard.  With no heel of the neck or body to guide you it does mean a lot more concentration.  Thumb position is a lot easier though without the body and with the added benefit of the intonation markers - some might think this is cheating!

Anyway, thanks once again and I'll have no hesitation in recommending your business to other bass playing colleagues.
