I recently switched to the Sm4M Ultra mouthpiece

It was only a matter of seconds before i realized i had made the right choice. My sound opened up in a matter of seconds and my generally timid higher register became full and rich with colour. In a short time with the SM4M Ultra, i have discovered a beautiful sound. Beware, if you try this mouthpiece, you may not want to put your horn down.
