Josef Klier - Highest Quality From Master Craftsmanship!

JK Exclusive mouthpieces deliver large tonal output, pure intonation, effortless response, and precisely calculated resistance in the cup profile and backbore, ensuring the player solid endurance.

A musician's personal sound ideas and wishes can only be met with the utmost technical precision. That's why Klier uses CNC-controlled turning machines to produce their JK mouthpieces. Only this manufacturing method, with its high positioning accuracy, achieves the serial precision required with tolerances in the micron range (thousandths of a millimeter).

Unique in the Mouthpiece Sector

The consistent rim and cup diameters within each series, combined with the exact and graduated adjustments, allow the player to achieve any desired style without having to change their embouchure. A mouthpiece series worked to such precise and optimal standards cannot be found in any other mouthpiece offering.

To say it in advance: I prefer to play my flugelhorn with the mouthpiece 5 BFL from Warburton, because it produces a voluminous and classic tone due to the deeper cup and the larger bore.
But when playing longer and in higher pitches I reach my limits as an amateur musician.
Therefore, I was looking for a similar mouthpiece, which fulfills the aforementioned characteristics, but can also cover the entire range better.
After some tests I came across the large product range of Josef Klier, which offers a huge choice with differentiated gradations of mouthpiece sizes. I found what I was looking for with the Exclusive 6 F mouthpiece: Sound, response, especially in higher registers are good and the soft and warm flugelhorn tone is also still achieved. Originally I favored the 5 E or F. In the end, however, the wider rim of the 6 series (5.25 mm) tipped the scales.
Overall, I am very satisfied with the JK mouthpiece Exclusive 6 F and gladly award the highest score for response, sound and workmanship.
In the future I will change my trumpet and cornet mouthpieces to the Josef Klier series as well. This will make it easier to switch between the instruments without any problems.
