Josef Klier Signature Mouthpiece H. Kobler for Tenor Horn!
JK Exclusive mouthpieces stand out with large tonal volume, pure tuning, easy response, and precisely calculated resistance in cup design and backbore, ensuring good endurance for the player.
The personal sound concepts and wishes of a professional musician like Harald Kobler can only be fulfilled with the highest possible technical precision. That’s why Klier in Diespeck, Middle Franconia, uses computer-controlled CNC lathes to manufacture their JK mouthpieces. Only this production method allows the necessary series accuracy with tolerances in the micrometer range (thousandths of a millimeter) thanks to its high positioning precision.
Unique in the Mouthpiece Sector
The consistent embouchure and cup diameter of each series, along with the exact and differentiated gradation, allow the musician to achieve any desired style without having to adjust their embouchure. A mouthpiece series with such precise and optimal craftsmanship can’t be found in any other mouthpiece offering.
The Conclusion of Professional Musician Harald Kobler
"In search of a mouthpiece manufacturer that combines quality, innovation, and humanity, I found my match with Klier. Together, we developed a Harald Kobler Signature mouthpiece series for trombone, tenor horn, baritone, and valve trombone / bass trumpet. All mouthpieces feature the rim contour 6-1, which greatly facilitates switching between different instruments or mouthpieces.
As a tenor horn player with the 'Innsbruck Bohemian - the Original,' I’m happy to have developed the TH 6DB-1 H. Kobler mouthpiece, which supports me throughout the entire playing range and fully satisfies my sound expectations.
The modified backbore produces a full yet clear, direct tone. This especially convinces me when playing in small ensembles and blends very well in larger Egerländer groups."
