Getz did have a particularly dark horn but the reason you have your "Getz-esque" sound is because Getz was the master of a technique called subtone. He played, often, very soft and using his subtone gave it that smooth dark feel. However, I do not want to deter you in your quest for a great sax. Getz used a Mark VI Tenor(I think exclusively). A saxophone that has more of the spirit of the Mark VI would be the Reference Tenors also made by Selmer. They have much of the same tone of the old five digit VI's but I urge you to try it out before you decide anything. If anything go to your local music store and try the Series III and the Reference side by side. Good luck in finding your "Getz-esque" sound. Cheers, Dark Eyes (unloved thesis)
