They needed to joint ash/alder and mahogany to get a more accurate recipe, even adding a half inch maple cap to the mahogany if you want to get closer to the LP sound. I actually dig the concept, but I might have flipped the necks...maybe not...who the fuck knows. I'll take one.
Yep, more practical than any other double neck I've seen. That doesn't mean I want it.
I'd rather have a banjo and baritone Dano double neck, just to fuck with people.
