Conn 20K Sousaphone
BBb marching sousaphone
Tuba · United States
The C.G. Conn 20K is the original BBb sousaphone, derived from concepts by John Philip Sousa in the early 1900s. It features a 26-inch brass bell, a .734-inch large bore for the sought-after marching sound, heavy-duty bracing, and offset short-action pistons for improved ergonomics.
