Yamaha Douglas Yeo Signature Series Gold plated Trombone Mouthpiece
Mouthpieces designed and used by Alain Trudel and Doug Yeo.

The Douglas Yeo Signature Series mouthpiece features a large, symphonic size cup for a big, rich sound. It is characterized by a full, centered tone with a focused core; a brilliant, well-defined overtone series; and an even response in all registers and dynamics. It combines the best aspects of large, symphonic style mouthpieces with an ideal amount of outer mass and a carefully designed backbore and throat for improved high range and dynamic flexibility. Gold-plated rim and cup.
