I use the sax since 1970 is now 39 years. Buffers and the mechanics are original. What we look for in a sax is the sound. That this super Dynaction was at that time my preference to another soprano saxophone (another very famous French brand), because its sound is warm and nonaggressive. It is versatile and can play all styles of music. I will never part with it is to say how much I appreciate it for its tone and strength.
