Mica,
What a memory! Yes that matches what Peter (orig owner) told me; he took two trips out there from Chicago to handpick the woods, I guess in 96-97 the internet wood bank wasn't available. Good thing, since I have been having trouble concentrating while voraciously consuming the pix you have posted there.
I thought at the time Peter said it was burled walnut, but the paperwork agrees with you: burl rosewood. He told that this piece was reserved for a 25th Anniversary bass, and that there wouldn't be many like this one. He was right.
