Building upon the success of the model 33-T, Kanstul decided to offer the option of a 4-front-piston/5th rotor professional BBb tuba. With hand-lapped upper slides that offer smooth and easy adjustment, vented pistons and Kanstul’s patented controlled-resistance rotor, this tuba offers the best in both traditional craftsmanship and modern innovation. This tuba is also available as a 4-front-piston tuba on special order at the same price as the 33-T.
