Left shoulder convertible concert/marching tuba.
The Jupiter 380L Convertible 3/4 BBb Tuba is a left shoulder convertible marching/concert tuba that is an excellent choice for when you want one horn that works well for both concert and marching band. The 380L features a .661 inch bore for outstanding tone and response from a 3/4 size instrument.
The Jupiter horns make it easy to afford to have good concert equipment as well as fully functional marching instruments. When in marching set up these horns put out a lot of sound and are easy to carry. Why spend the money in having separate concert and marching instruments when you don't have to?
