Josef Klier - Highest Quality From a Master's Hand!

JK Exclusive mouthpieces deliver big tone, pure tuning, easy response and precisely calculated resistance in cup design and backbore, giving the player solid endurance.

The player's personal sound ideas and wishes can only be met with the highest possible technical precision. Therefore Klier uses CNC-controlled turning machines to produce their JK mouthpieces. Only this type of manufacturing method, thanks to its high positioning accuracy, enables the required production consistency with tolerances in the µ-range (thousandths of a millimeter).

Unique in the Mouthpiece Sector

The consistent rim and cup diameter across the series, together with the exact and differentiated gradation, allow the musician to reach any desired style without having to change their embouchure. A mouthpiece series of such precise and optimal workmanship cannot be found in any other mouthpiece offering.

This is the mouthpiece I have. With it I can play pieces where I already wanted to give up. The service is just great. I can only recommend the Kirsten company. The music house is my first choice from now on.
