Yeah, looks like something I would have made out of random parts! I think that's the origin of a lot of so called prototypes. They often have no record of their pedigree and it's usually bogus.
But, I still think it's a cool looking little bass! I have some ideas for an LP style bass myself, including the nice bevel around the edges and maybe even an f-hole of sorts. Can't wait for summer, I'm off June till September!
