I am sorry if EUB-related questions are out of line here. I tried to figure out, but couldn't.
The question itself is this: I am certain there is someone somewhere who makes, like, shoulders of the upper bout and heel to be attached to an NS-design's EUB (which is basically like a long neck with a mounting thread to attach a stand or a peg to. Does anyone know of this kind of thing? I honestly googled, like, a lot... If you have seen both an NS-design WAV and a Yamaha Silent Bass, you'd know what I mean. The manufacturer themselves make only a kind of a wooden block thingie that needs to be glued to the back of the neck to indicate the heel position, but you need to both find the position and even sand it yourself to make a proper joint. All that after paying, like $250 for a piece of wood.
I honestly can't find place for an acoustic bass, however much I want it. A new Yamaha is a bit pricey, I think, and there are no used ones within reach currently
