The Besson BE995 CC Tuba represents the first time Boosey & Hawkes has produced a front-action, 5-valve full size CC tuba. The BE995 is an exceptional professional instrument with a "four piston, one rotary" non compensating valve configuration. It is a highly efficient instrument with a wide dynamic range and a powerful low register, this tuba provides maximum sound output with less effort than other makes of CC tuba.
