TUBARVB 4-Rotor Tuba – Bb

As with all Jean Baptiste brass instruments, the TUBARVB 4-Rotor Tuba is designed to provide the exceptional quality and value that defines Jean Baptiste.

The full size TUBARVB is a contrabass tuba keyed to Bb, the most widely used key among student and marching band tubas. Its .750″ large bore gives the advancing player a greater amount of control, while reducing resistance. TUBARVB is fitted a with a 16.75” yellow brass bell and yellow brass body for commanding projection and rich even tone. Its yellow brass leadpipe helps deliver a smooth, mellow tone. In addition, the TUBARVB’s four yellow brass rotors offer players a far greater range of control over a tuba that utilizes valves. Featuring nickel silver construction for the outer tuning slides, the TUBARVB is solid and reliable at the parts of the instrument that see the most movement and adjustment.

The TUBARVB comes complete with a wheeled case, 24AW mouthpiece, bottle of valve oil and microfiber polishing cloth, allowing the instrument to be continuously maintained.
