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 design and backbore, giving the player excellent endurance.

The performer’s personal sound ideals and wishes can only be met with the utmost technical precision. For that reason Klier uses computer-controlled CNC lathes to manufacture their JK mouthpieces. Only this production method, with its high positioning accuracy, achieves the required series precision with tolerances in the micron range (thousandths of a millimetre).

Unique in the Mouthpiece Market

The consistent rim and cup diameter across each series, combined with exact and differentiated gradations, allow the musician to reach any desired style without changing their embouchure. A mouthpiece series of such precise and optimal workmanship cannot be found in any other mouthpiece range.
