Josef Klier - Highest Quality From Master Craftsmanship!
JK Exclusive mouthpieces deliver big tonal volume, pure intonation, easy response, and precisely calculated resistance in the cup and backbore, giving the player reliable endurance.
A musician's personal tonal preferences and wishes can only be met with the utmost technical precision. That's why Klier uses computer-controlled CNC lathes to produce their JK mouthpieces. Only this manufacturing method, with its high positional accuracy, provides the series precision required with tolerances in the micrometer range (1000ths of a millimeter).
Unrivaled in the Mouthpiece Sector
The consistent embouchure and cup diameters across the series, together with the exact and differentiated gradations, allow the musician to achieve any desired style without having to change their embouchure. No other mouthpiece range offers such precise and optimally crafted models.
