I studied with George some years ago. At that time, he was playing a Selmer Mark VI with a New York Meyer 5M, La Voz MH reeds, stock ligature. I take it from his last CD that he made the switch to a Yamaha Custom alto.
George left Bern, Switzerland to Lausanne, Switzerland where he is now head of the Jazz School. He's very busy playing all around the world. Fantastic musician, great teacher, nice guy.
Acutally, George's mother was American which makes him half Swiss, half American.
