Josef Klier - Highest Quality From Master Craftsmanship!

The family business traces its roots to Graslitz in the Sudetenland, the town considered the cradle of instrument making. That's where the development of the entire trade began. As early as 1669, 12 master violin makers were working in Graslitz. By the outbreak of World War II there were 300 companies employing a total of 3,000 trained instrument makers.

JK Mouthpiece "USA Line"

What sets the JK USA mouthpiece line apart is its different cup shape. They are based on patterns the Army bands brought back from Mount Vernon, New York. Josef Klier discovered the mouthpieces after World War II and fell in love immediately: the USA Line was born. Roland Klier then produced faithful copies, which the Army musicians enthusiastically adopted.

A musician's personal sound preferences 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, thanks to its accurate positioning, achieves the necessary serial precision with tolerances in the micrometer range (1/1000 mm).

Good to Know:

  • Backbore A1: small, tight backbore
  • Backbore A2: medium backbore (standard)
  • Backbore A3: larger, roomy backbore

For passionate brass players who love their instrument!
