These mouthpieces are made to each specific player's specifications. Measurements such as inner diameter, venturi, etc., are not arranged systematically, however this line is also numbered progressively by cup depth from deep to shallow.
Each of our endorsees chose a Marcinkiewicz Designer/Signature Mouthpiece because of their belief in the product. Each of these mouthpieces were designed for a specific player at a specific point in time. Many play our mouthpiece exclusively
The mouthpiece arrived in mint condition! It has been exactly what I was looking for.
Dillon Music was quick to respond and sent the MP in a timely manner.
I have used many mouthpieces over the last 30 years. Played Shilke for a long time. These are by far the best sounding and most responsive mouthpieces I have used. Dillon music was extremely helpful in getting me the one that I wanted and did an excellent job of gold plating it for me. I will definitely be a return customer!
