We are excited to release our newest mouthpieces to our low brass line.   Working with several professional and also hobbyist euphonium players, Greg and team developed the new "290" Series Euphonium Mouthpieces from some of our already extremely popular rim and cup sizes but with a different feel and balance more suited for the needs of the performer.  The resulting sound has a richness, wider spectrum of overtones and depth that we think you will love!
