Built to project across stadium stands and outdoor venues, the Adams MSP1 series marching sousaphone delivers steady intonation and a commanding low register for competitive marching performers. Its .748" large bore and 26" yellow brass bell provide focused projection that cuts cleanly through full ensemble volume, while the oversized outer wrap balances naturally on the shoulder to reduce fatigue during parades, drills and game-day shows. A removable stainless steel valve block keeps response fast and reliable through long rehearsals, and your choice of lacquer or silver plate finish offers both durability and visual presence on the field. Each sousaphone ships with a 24AW mouthpiece and a protective SKB wheeled case, supporting confident tone from day one and safe transport between practice and performance.

Adams Construction Built for the Demands of Marching

Designed for players who spend hours on the field, this sousaphone pairs strong breath support with durable, low-maintenance hardware. The large bore helps players produce a powerful, centered tone that carries across open outdoor spaces, while the yellow brass bell adds brightness to keep the low end defined within the band mix. Stainless steel pistons resist sticking and wear even in changing weather, and the SKB wheeled case protects the instrument from dents and damage when moving between rehearsal spaces, buses and stadium environments. Season after season, the Adams MSP1 delivers reliable projection, clean articulation and field-ready strength that marching musicians can depend on.
