Josef Klier - Highest Quality From Master Craftsmanship!

JK Exclusive mouthpieces deliver big tonal volume, pure intonation, easy response, and precisely calculated resistance in cup shaping and backbore, giving the player reliable endurance.

A musician's personal tone concepts and wishes can only be met with the highest level of technical precision. That's why Klier uses computer-controlled CNC lathes to produce their JK mouthpieces. Only this manufacturing method, with its precise positioning, achieves the serial accuracy required with tolerances in the µ-range (thousandths of a millimeter).

Unique In The Mouthpiece Sector

The consistent rim and cup diameters across the series, together with the exact and differentiated graduations, allow the musician to reach any desired style without having to change their embouchure. A mouthpiece series of such precise and optimally developed design is unmatched by any other mouthpiece range.
