It's chinese rosewood (use for making antique furniture). It's finished with clear lacquer instead of the usual red u see on furnitures.

Very nicely done! and those Pass Labs brass plaques...I bet Nelson's lawyers are smelling blood!

What's with the stickers? Are you planning to market it or you are just a very forgetful person?
