Rosewood is a protected species under the CITES treaty, so I don't expect any new wood to be available unless someone discovers something 20 years old in their warehouse. We've only got enough to finish the Sterlings, so we're saving it for those.
I've got some other interesting burl woods though. We've got 2 pieces of Burl Madrone at are big enough to make doors out of. Would even make a nice single-piece top for a 6-string Series II bass. Burl Myrtle and Maple galore. Nice stuff too!
Amboyna Burl is quite delicious, orangey and yellows, sorta looks like boiling butter.
There's two burl rounds we've got in stock but have never used on an instrument, so I have really no idea what they will soud like. One is Bing, a wood from Indonesia that our wood supplier icked up a few piece of on his last trip there. Then there's the Tazmanian Eucalyptus Burl, it sort of resembles medium brown burl oak, but is much less dense. I'm curious to discover what these will sound like.
