The DAddario Select Jazz Marble Tenor Saxophone Mouthpiece is a uniquely stylish mouthpiece designed to evoke the sound of vintage jazz mouthpieces. It is milled from solid rod rubber rather than moulded using computer-controlled technology to precisely manufacture each mouthpiece to the same standard. This model is capable of achieving a classic sound and response with even intonation across the saxophones range. This mouthpiece has a medium-sized chamber and facing length with a narrower tip opening of 0.100″ – which allows for more accurate intonation and easier access to the higher register perfect for precise players and soloists. With its fantastic classic sound and limited edition marbled finish you know youll be turning heads using this mouthpiece.
