It's beautiful.!!!. But I doubt there is any luthier on the planet that can tell what wood it is from some pictures. Ive seen rosewood that looks like cocobolo. Its wood. All grain in certain species is different, depends on the tree that it was cut from.. I have a Sei Jazz that I know has a brazilian rosewood fret board, and it doesn't look like Brazilian rosewood.
Like I said that is a beautiful neck wood. Its a one piece neck I presume.? It certainly looks like Cocobolo with that swirl in the grain.
