Have you seen Moldover's other gear? The guitar looks perfectly usable -- for him. He makes these ingenious contraptions that only he can use. They're really cool and I'm sure you could learn how to use it with enough practice, but it would be a lot of effort to learn how to use a pretty much one-of-a-kind tool. I wonder if he sold all his Mojos - I considered buying one at one point but decided my tastes were slightly less exotic.
