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 profile and backbore, giving the player reliable endurance.
A player's personal tonal vision and preferences can only be met with the highest technical precision. That's why Klier uses computer-controlled CNC lathes to produce their JK mouthpieces. Only this manufacturing method, thanks to its fine positioning control, achieves the serial accuracy required, with tolerances in the µm range (thousandths of a millimeter).
Unique in the Mouthpiece Sector
The consistent rim and cup diameters of each series, together with the exact and differentiated gradation, let the player achieve any desired style without having to change their embouchure. A mouthpiece series of such precise and optimally crafted design cannot be found in any other mouthpiece offering.
