The "original" sousaphone - the C.G. Conn 20K originated from the concepts of John Philip Sousa in the early 1900's. This .734" large-bore sousaphone has the most sought after sound for the marching field, and standard heavy-duty bracing gives the 20K the durability for years of performance. Offset short-action pistons improve ergonomics and technical facility.
