Josef Klier - Highest Quality From a Master Craftsman!

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

A musician's personal sound ideals and wishes can only be met with the highest degree of technical precision. That's why Klier uses computer-controlled CNC lathes to produce their JK mouthpieces. Only this manufacturing method, thanks to its highly accurate positioning, provides the serial precision required with tolerances in the micrometer range (thousandths of a millimeter).

Unique in the Mouthpiece Sector

The consistent rim and cup diameters across the series, together with exact and finely graduated variations, allow the musician to achieve any desired style without having to change embouchure. No other mouthpiece range offers such precise and optimally developed workmanship.
