The CBB3123 is a ¾ B-flat tuba with three front-action piston valves. Designed for the beginner tubist, the CBB3123 is a lightweight and more compact alternative to a full size 4/4 tuba for elementary and middle school students. Front-action valves set up the student for a transition to a rotary or piston valve tuba and allow young students to adjust slides for improved intonation at a young age. The 15.75” bell provides a rich full sound and open low register not typically found in a ¾ tuba.

Outfitted with a hardshell ABS case and Bach 24AW mouthpiece, the CBB3123 is available with a lacquer finish.
