The Kenny G Power Chamber Hard Rubber Soprano Saxophone Mouthpiece is very unique. The inside chamber is patterned after the mouthpiece Kenny G plays . The use of the Hard Rubber makes it easier to play with a great sound. Kenny G and Rheuben Allen spent a lot of time in researching and testing to come up with the best material for a great sounding mouthpiece. The KG Soprano Mouthpiece offers similar characteristics of the mouthpiece Kenny G uses. With the addition of the Rovner Ligature, it gives the mouthpiece a rich, balanced tone color, and great response though out the Saxophone.
