The type of rosewood I have heard used were Dalbergia latifolia- east indian, and sonokeling rosewood from Indonesia, on narrow elb's. I'm sure Brazilian rosewood would have been used in the past, and is probably performs even better if you can get hold of some post CITES import ban. Rosewood is a fairly generic description including many timbers that aren't dalbergia, like bubinga, PNG rosewood, Australian rosewood.
