This euphonium features a 4 compensating valve design with a traditional 3 Top and 1 Side action valve set. The M5050 features a specially designed heavyweight receiver to focus the sound and a gold brass mouthpipe for better note slotting. The Miraphone M5050 Ambassador Series Compensating Euphonium includes a case and large shank mouthpiece and is available in silver finish in a standard design (M5050) or with a main tuning slide trigger and guard (M5050T).
