THANK YOU! Unfortunately, I'm no position to sell the thing. I'm just a bass player that had an idea. It just so happens that my wife's uncle is an excellent craftsman, and he built it for me. But, I can't burden him with building too many of them. In fact, I almost felt bad asking him for a couple more - just 2 more. He agreed, but honestly it feels like I'm pushing my luck. LOL!
My dream is to get it licensed. Maybe Warmoth, or All Parts, or any other guitar parts/accessories manufacturer will "buy the rights" from me and mass produce it.
As it is, I think almost anyone can build at least a good semblance of it. The thing itself is relatively simple to make, it's the idea behind it that seems to have eluded us all for so long. So, as long as people don't claim ownership of the idea and/or start to sell them without crediting me, I'd have no problem if someone built one just for him/herself.
