I own one bass made of calantas (top, back and ribs). Calantas is a kind of cedar which grows in Malaysia/Indonesia/Philippines, sometimes called Malaysian Red Cedar.
Not much more than a year old, this bass has a truly gorgeous tone, both arco and pizz, rich harmonics all over the place, and window-shaking power. The Moscow Symphony came through town recently, and found themselves a bass or two short, so I rented this to them. The principal chose to play my bass, it sounded fantastic in his hands, and its distinctive, lovely tone came through clearly, esp in div passages. When the instrument was returned, I received a hand-written note which went on for a whole page in slavic-tinged English praising the sound of this wonderful bass.
Just goes to show that great sound can gotten out of materials other than the standard woods.
