Awwh chucks, I should've demand a percentage.... regret I posted the idea here.
The most important thing is though: Since everyone reads it, you'll have to hurry up because you'll definitely be the FIRST ONE out there, to pursue this feature.
Get a patent on it! Test in on a fretless bass. I find it quite peculiar that Moog/Paul Vo hasn't produced a bass version yet. The most important thing is to KEEP the sustainer too. You should be able to switch between them functions. Either/or is not that a good idea. Both. Because I think, as it works now, there are alternatives out there already, that can produce infinite sustain. I think Michael Brooks (film score composer, avant garde guitarist) did some infinite sustain things before anyone else (Fernandes, Sustainiac et al). To be used on both guitar and bass.
Try it with a fretless with flatwounds on. If you have access to - say - neodymium pickups passive or active that can track a couple of more frequencies than any passive alnico/ceramic pickup it will be better. Trust me on this. Even if the bass has flatwounds on it which doesn't give away that much treble. It's all about the initial attack of the note. WHEN the string is plucked. It's the FEEL of the strings stopping dead right of them being plucked that is same as an upright. Having the string ringing and oscillating, you could as well plug it into a sampler/or a synthesiser with an upright bass patch/preset and leave it at that.
However, I think...it requires more power to be able to oscillate large bass strings (and stop them!), so no 9 v battery would be sufficent enough. 18 v maybe? Two 9 volts?
I can at least become the betatester and get a unit for free, if it should catch on....

While you do this, the other guys can try building something like this to "go" with it then:
Fishman and others has produced this FISHMAN AURA box that contains modelling samples of different high end acoustic guitars, and sample them at 2.000 points, and blends in with piezo pickups. To use with acoustic guitars live, to get a nice sound without feedback. However, this has only to do with the acoustic properties of the acoustic guitar recorded/sampled with high end mics in high end studios.
NOW PEOPLE: Think of the exact same process, but done to an upright bass's acoustic top. A great and enormously expensive old 18th century italian bass, or similar, recorded and put samples in that box. Then you have that "aural" properties of it. Added on top of the "anti-sustain" properties of your box. I don't know if the Fishman Aura today, already has this feature. I've heard something that you can send in your own guitar and get that "template" of the soundboard, top of the guitar. On a sampled file or something and load it into the Fishman. I don't know if this would work out on an upright bass though. Those upright basses are major dough...
Of course, the most convenient thing would be to combine them in one bass (i e the non-sustaining bit plus aura) , but it would turn out quite unwieldy I think. Cumbersome as hell.
