Josef Klier - Highest Quality from Master Craftsmanship!
JK Exclusive mouthpieces stand out for their large tonal power, pure intonation, easy response and precisely calculated resistance in cup profile and backbore, which gives the brass player excellent endurance.
The player's personal tone preferences and wishes can only be met with the highest possible technical precision. That is why Klier uses computer-controlled CNC lathes to manufacture their JK mouthpieces. Only this production method, thanks to its high positioning accuracy, achieves the necessary series precision with tolerances in the µm range (thousandths of a mm).
Unique in the Mouthpiece Sector
The consistent embouchure and cup diameters within each series, together with exact and finely graded variations, allow the musician to reach any desired style without having to change their embouchure. A mouthpiece series with such precise and optimally executed workmanship cannot be found in any other mouthpiece offering.
