Josef Klier - Highest Quality From Master Craftsmanship!

JK Exclusive mouthpieces deliver powerful tone, clean intonation, easy response and precisely calculated resistance in the cup throat and backbore, giving the player dependable endurance.

The player's personal sound ideas and wishes can only be met with the highest level of technical precision. That's why Klier uses computer-controlled CNC lathes to produce their JK mouthpieces. Only this manufacturing method, with its exceptional positioning accuracy, achieves the necessary production consistency with tolerances in the micron range (0.001 mm).

Unique in the Mouthpiece Sector

The uniform rim and cup diameters within each series, together with the exact, differentiated gradations, allow the musician to achieve any desired style without having to change their embouchure. You won't find a mouthpiece series with this degree of precision and optimal workmanship anywhere else.
