I have been playing sax for about 7 years and I want to upgrade my current sax (A Yamaha YAS-25). I recently went to a local saxophone dealer who has hundreds of used saxes and after about 3 hours, I had finally narrowed the choice within my budget to either a Keilwerth SX90R (made in about 1992) or a Selmer Super Action II (only a year old ie. 2009). I have found that the Selmer gives a much fuller tone, but the Keilwerth's tone is more distinctive, but a little more 'tinny'. I play mainly Big Band and Quartet (Sax, Keys, Bass, Drums) Jazz and I really like both of these saxes and cannot choose between them. I'd really appreciate anyone's opinion on these two saxes, thanks.
