Most unique feature in the design is the strings wrapping around and anchoring the back of the body, some where in the middle. You notice that they didn't show the back of the bass in the photos... That really makes the bass growl and sustain like a fretless electric with ultra light and rubbery strings, different than any other. That feature also might present problems with tuning stability. Honestly, for all the trouble of building a custom instrument and dealing with trial and error process, a NS bass will prolly be superior in all other aspects of design, fingerboard shape, electronics, ergonomics, case, stand, ect.
