"A step beyond
the traditional top valve tuba models, the Besson Sovereign
BE993 BBb Tuba incorporates a front valve action mechanism.
A popular design, front action valves offer greater comfort
and movement to the player. The valves are bottom sprung and
work in conjunction with a spring damper set so valves work
more efficiently and quietly. The BE993 BBb Tuba is fully
compensating and produces a clear full sound throughout the
registers. Two carriage rings, an adjustable thumb ring, and
three water keys make this tuba comfortable to play"
