F Tuba · Model 155

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 (Model 163 also available as C-instrument) are manufactured with four valves. Extra (auxiliary-) valves or individual pipe lengths for auxiliary valves are realizable on request.

Model 155 is also available with an additional valve for lowering pitch by a perfect fifth after the main tuning slide.
