During the development of his new tenor saxophone Friso seeks input and feedback from the world’s best players to further improve his instrument. This week Branford Marsalis visited our workshop where played and tested our tenor. After having played the instrument at our shop, Branford was willing to test the instrument live on stage. So the next day Friso went over to Germany to hear Branford play a beautiful outdoor concert (his quartet was accompanied by Kurt Elling) on our new tenor prototype.
