WILLSON Bass Trombone 550TA

This in-line "independent" trombone 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.
