New B&S GR51 Professional BBb tuba
The new B&S model GR51 is a 4/4 size BBb rotary tuba that is based on the legendary tubas that were once built in Graslitz, Austria. Its bell has a larger and faster taper than other tubas in its class; the result is a punchier sound and easier maneuverability throughout the range.
The GR51 features an “open wrap” main tuning slide that gives it a rich sound color in the best German tradition, with smooth response and evenness over the entire range. The low register is highly efficient and the upper-middle- and high register are particularly secure. Indeed, the scale is exemplary in terms of intonation, tonal balance and response, all combined in an outwardly compact and easy-to-handle package.
All B&S professional tubas with rotary valves are equipped with 3B ball bearing linkages on both ends of the valve connecting arm to provide the ultimate in smooth, quiet operation. The GR51 sounds much bigger than you would expect from a typical 4/4 tuba. It comes complete with gig bag and accessories. This is the next standard in 4/4 BBb rotary tubas.
