The two I have built so far both have jatoba necks, as will the one I'm just starting.
first build
Hook Custom
They are extremely stiff responsive necks that feel and sound great. And no neck dive issues with these anyway.
I think it would be too hard and heavy for a body wood, although it's not that different from bubinga in that regard. It is normally rather plain too, but if I ever ran across a piece of the proper size for a top that was figured like the one I pictured here, I'd certainly give it a go.
