Comfortable valves provide easy playability with a clear, bright sound.

The Jupiter JEP1101M 3-valve Marching Euphonium is a B-flat marching euphonium that produces a bold, projecting tone suited for advanced marching band performances. A yellow brass body and 11" bell generate resonant, authoritative sound that carries across stadiums and parade routes. The .592" bore and nickel-silver mouthpiece receiver of the JEP1101M provide a balanced tone with a bright, articulate attack. Stainless-steel pistons withstand outdoor playing conditions and offer a smooth feel with quick response.

Adjust Intonation On-the-Fly
First and third valve slide rings on the JEP1101M allow performers to make intonation adjustments quickly during play. The fixed ring design prevents slipping in various weather conditions, providing reliable intonation control rain or shine.
