JK Exclusive series
Many mouthpiece manufacturers work with model names that allow only insufficient conclusions about cup diameter, cup depth and rim contour. Roland Klier was quick to recognise the disadvantages this posed for players looking for their own mouthpiece.
In 1964, he designed the Exclusive line, a logical and easy-to-understand designation system that allows the player to see all the relevant data at a glance by means of the model number.
In addition, he develops a revolutionary concept in the combination of cup, bore and backbore, which makes it possible to use Klier mouthpieces in any musical style.
The unusually large selection in the Exclusive line offers every wind player the opportunity to find his or her personal mouthpiece. In addition, the rim contours of trumpet, cornet or flugelhorn mouthpieces are identical with the same cup diameter. This enables the player to change the mouthpiece quickly and easily.
The unique outer shape of the Exclusive series is the result of numerous attempts to work out the optimum mouthpiece weight. It has established itself as a distinctive feature of the JK Exclusive series.
The Exclusive-Export line is an addition to the respective Exclusive series. The rims are identical to the Exclusive series in diameter and rim shape to make it easy to jump between the series.
In terms of sound, the Export line is geared towards symphonic brass music and the classical brass band.
