Otto Link Metal Alto Saxophone Mouthpiece - New "Super" Tone Master.

Benny Carter used one on his alto, other notable players such as John Coltrane, Lester Young, Ben Webster and Buddy Tate played them on tenor sax. This is always a good option to try out if you are thinking of moving to a metal mouthpiece.Great to compare with some of the other USA custom mouthpiece makers such as Theo Wanne, Jody Jazz, Retro Revival, Drake etc
