Tuba Classic „Exclusive“

Mundstück Tuba

The new conical shaped cups of the Exclusive Classic Tuba Line have been developed from scratch.
Their large, well-balanced sound and excellent response across all registers is not just a sonic extensionof the existing Exclusive series with its apple shaped cup design. The rim contours have been retained in the new Exclusive Classic line, making it easy to switch between the two mouthpiece series.

Matthias Raggl

(state theater Nuremberg)

„The new conical cup shape of the Classic models avoids air congestion, offers easy and safe response in all registers. Especially the possibility of a gentle and even connection of the individual notes in the Legato convinced me.“

Prof. Hans Nickel

(WDR Sinfonieorchester)

„I‘ve known the JK Exclusive Tuba mouthpieces for a long time, but the new Classic Series is a real alternative. On the F as on the BBb and CC tuba, the new cup design conveys a rich, clear tone with excellent response across all registers. Especially the articulation in the depth is absolutely trouble-free. The Classic models are really recommended!“

Manfred Häberlein

(Harmonic Brass)

„I tested the new Exclusive Classic mouthpiece intensively and during the development phase I passed on my opinion and impressions to the specialists of JK. The now finished product is sensational. Finally, I have a mouthpiece that I can use in very delicate passages without a loss of sound. It centers excellently and thus ensures a precise and clear attack.“
