This is a 10MFan hard rubber Robusto 7** hard rubber mouthpiece for tenor saxophone. The piece is in great shape. Its facing profile is still in excellent condition regarding the table tip and rails. The tip opening on this mouthpiece measures .106”, this is just a little over the standard 7* opening in Otto Link measurements.
As the name suggest the sound quality of this mouthpiece is full and very robust. This is the piece to get if you are looking for the traditional hard rubber Otto Link vibe with just a little bit more power and fullness.
