Re: What can you tell me about the Conn 20M
They are a good student-intermediate model sax.
The 20M came out in the early 80's. After Daniel Henkin bought Conn, he returned production to Ekhart, IN and the 20M's were US made. They have a nice sound, and a pretty good action. You may want to try a different mouthpiece though. The Brillhart Ebolin is a great beginner piece, or the Selmer S80 C*
