C-Tuba · Model 173
Due to the incomparable and typical Alexander-sound and a relatively low weight, Alexander Tubas offer a very comfortable handling. Even the Kaisertuba (Model 164) weights only 9.75 kg which ranges distinctly below the usual weight classes.
The Bb tubas (also available as C-instruments) are manufactured with four valves. Extra (auxiliary-)valves or individual pipe length for auxiliary valve are realizable on request.
- Thumb valve for right hand (2 whole tones)
