Essentially a wooden Steinberger with a slip-on body, running the same P-bass-in-a-humbucker-shell EMG HB's. All the ebony would approach the hardness and tone of composites. Unfortuantely, it's not hollow . . . .
I would certainly suggest that whoever buys this beast head on down to REI or Bass Pro Shops and buy one of those 'Y'-shaped sticks you use as a brace with a scoped rifle to rest the head in once you strap this on, as I'm betting the neck will head for the ground quicker than your wallet did. This type of shape is always tempting, but . . . . gravity (or more correctly, center of gravity) rules.
12 Large? Really?
