Josef Klier - Master Craftsmanship!

JK Exclusive mouthpieces are defined by big tonal volume, pure intonation, easy response, and precisely calculated resistance in the cup and backbore, which gives the player reliable endurance.

A musician's personal sound ideals and wishes can only be met with the highest possible technical precision. That's why Klier uses computer-controlled CNC lathes to manufacture their JK mouthpieces. Only this production method, through its high positioning accuracy, delivers the serial precision required with tolerances in the micron range (thousandths of a millimeter).

Unique in the Mouthpiece Sector

The consistent rim and cup diameters within each series, together with the exact and finely graduated steps, allow the musician to achieve any desired style without having to change their embouchure. A mouthpiece series with such precise and optimally executed workmanship cannot be found in any other mouthpiece offering.
