Josef Klier - Highest Quality From Master Craftsmanship!

JK Exclusive mouthpieces stand out with large tonal volume, pure intonation, easy response and a precisely calculated resistance in cup design and backbore, which ensures the player excellent endurance.

A musician's personal tonal ideas and wishes can only be fulfilled with the highest possible technical precision. That's why Klier uses computer-controlled CNC lathes to manufacture their JK mouthpieces. Only this production method, thanks to its precise positioning capability, achieves the necessary serial accuracy with tolerances in the micron range (1/1000 mm).

Unique In The Mouthpiece Sector

The consistent rim and cup diameters within each series, together with exact and finely differentiated gradations, allow the musician to achieve any desired style without having to change their embouchure. A mouthpiece series crafted with such precision and optimal workmanship cannot be found in any other mouthpiece offering.
