As always every player is different and has different needs, therefore will need different mouthpiece designs to […]


New York
The NY blank weighs slightly more than modern day Bach mouthpieces (Elkhart blanks). Its weight is distributed evenly around the bottom of the cup. This results in an even core of sound with overlapping overtones, creating a tone quality that is thicker than conventional mouthpieces. The NY also provides the midrange overtones that are often lost with other mouthpieces.
The Deco blank is heavier in mass than the NY blank. The added weight is great for large bass trombone mouthpieces that may have thinner walls due to larger inner cup diameters. It is very free blowing and can provide a bigger, darker sound than mouthpieces with less weight. The Deco also provides stability, which can help define partials on those trombones where extra focus is needed.
Our newest mouthpiece blank, the Nouveau was created to give trombonists the flexibility a lighter mouthpiece can provide. It provides a width of sound and wider partial feel for a natural playing experience. Every tone and timbre can be manipulated, making the Nouveau a very expressive mouthpiece.
