Front action valves & upright bell.
The Jupiter 474 Euphonium is ideally suited for either the school concert band or individual performer. It has exceptional tone and intonation combined with responsive concert-style front action valves. It is one of the few front-action valve horns with an upright bell. Usually to get front-action valves (which some feel make it easier to hold the horn) you have to settle for a front-facing bell. Not any more.
