Donny...interesting. It's obviously a home made contraption...fretless...looks like two pipes for the neck and three strings. Bottom one is probably a bass string of some kind. Can't tell about the pick-up(s) but sounds like it might be a piezo of some kind.
there are a bunch of odd-balls from minor manufacturers, like the one I just bought (UGH), but this is a little rougher than that.
