Josef Klier - Highest Quality From a Master's Hand!
JK Exclusive mouthpieces deliver big tonal projection, pure intonation, easy response, and precisely calculated resistance in cup contour and backbore, giving the player reliable endurance.
A musician's personal tonal preferences and wishes can only be met with the highest possible technical precision. That's why Klier uses computer-controlled CNC lathes to produce their JK mouthpieces. Only this manufacturing method, with its high positioning accuracy, 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 within each series, together with exact, differentiated gradations, allow the musician to achieve any desired style without changing their embouchure. You won't find a mouthpiece series with such precise and optimally developed workmanship anywhere else.
