WILLSON Bass Trombone 551TA

This OpenWrap "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 over-scaling.

The mechanism is equipped with a smooth, precise and noisefree Rotohead system.
