I just got an unasked for catalog from a woodwind mail-order place. It has an intriguing item called a "Jim Brock Sax". It consists of a saxaphone mouthpiece and a bamboo body with some holes in it. They claim you finger it like a bamboo flute but it has a "deep dark sax sound". Has anyone had experience with one of these? I would be interested in comments and details such as what is the fingering for a bamboo flute compared, say, to a recorder or pennywhistle. Who is Jim Brock, anyway?Murray
