At Yamaha always make sure that quality comes first. This is also the case with the mouthpieces from the standard series. The ebonite mouthpieces for saxophone are made of phenolic resin. This ensures that the mouthpiece has consistent playing and sound characteristics. The track length is slightly longer than with the 3C and because of this you blow a balanced tone in all octaves. Suitable for both beginners and advanced saxophonists.
