We've been receiving your comments on the new 'M' shank Ultra mouthpieces. Here's the first:

"I recently switched to the SM4M Ultra mouth piece. It was only a matter of
seconds that I realized I made the right choice. My sound opened up in a matter
of seconds and my generally timid high 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 mouth piece, you may not want to put your horn
down!"
