Josef Klier - Highest Quality From a Master's Hand!
JK Exclusive mouthpieces deliver big tonal volume, pure intonation, easy response, and precisely calculated resistance in cup profile and backbore, giving the player excellent endurance.
The player's personal tonal expectations and wishes can only be met with the greatest possible technical precision. That's why Klier uses computer-controlled CNC lathes to manufacture their JK mouthpieces. Only this type of production method, with its high positioning accuracy, enables the required serial precision with tolerances in the micrometer range (thousandths of a millimeter).
Unique in the Mouthpiece Sector
The consistent rim and cup diameters within each 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 is not found in any other mouthpiece offering.
