WILLSON Bass Trombone 511TA

This OpenWrap trombone features the sensational ROTAX valves. There is room for the ROTAX rotor in a conventional valve casing and yet it still provides 100% air flow thanks to its compensated flow geometry. The ROTAX rotor has no troublesome constrictions and over-scaling.

The mechanism is equipped with a smooth, precise and noise-free Rotohead system.
