Josef Klier - Top Quality from Master Craftsmanship!

JK Exclusive mouthpieces stand out with large tonal volume, pure tuning, easy response, and precisely calculated resistance in bowl design and backbore, ensuring the player excellent endurance.

Klier Exclusive Classic

JK Mouthpiece Exclusive Classic

The newly developed conical bowls of the Exclusive Classic tuba line offer a large, balanced tonal volume and excellent response across all registers, making them not only a sonic extension of the existing Exclusive series with apple-shaped bowl design.

The rim contours were retained in the new Exclusive Classic, allowing easy switching between the two mouthpiece series.

Professionally Crafted

The personal sound preferences and wishes of the musician can only be met with the highest possible technical precision. That’s why Klier uses computer-controlled CNC lathes to manufacture their JK mouthpieces. Only this production method enables the necessary series accuracy with tolerances in the micrometer range (thousandths of a millimeter) thanks to its high positioning precision.
