WILLSON BBb Tuba 2-454 RZ-4

This tuba features the sensational ROTAX valves. There is room for the ROTAX rotors in a conventional valve casing and yet they still provide 100% air flow thanks to their compensated flow geometry. The ROTAX rotors have no troublesome constrictions and overscaling. The mechanism is equipped with a smooth, precise and noise-free Rotohead system.

The complete rotary unit can be dismounted.
