You're not alone anymore. This bass has found it's way to Sweden as well. I bought the pig in a poke, and I'm very disappointed
I don't think it's a prototype, and I don't think it's crafted in Japan. All the parts on my bass seem original and can be found on the link below. My guess is that it's Korean. The bass seems to be an older and simpler version of the Supernova ZI. [Invalid or Expired Link Removed]
I'm afraid I can't give a rave review. The neck is bent at the 10th fret (quite sharp, not a normal curvature) and impossible to adjust with the truss rod. I've never come across a wooden neck this hard. It's almost as stiff as my aluminium Kramer. I have to find a (cheap) way to get it straight. Except for this major flaw, the wooden parts seem to be of good quality and crafted fairly nice. The hardware is cheapish Korean stuff from WooSung Chrous Industries.

To my taste, the "LJF" pickups don't sound good wired in series (no treble at all, and not a nice p-bass sound either). They sound OK in parallell, either as is or the two outermost coils (j-bass sound) or the two innermost coils (MM-type of sound). If I can get the neck straight I'm going to rewire it like this.
