The DEG model 575 marching euphonium is an instrument designed specifically for the rigors of the marching environment. Extra bracing and solid construction are the key differences, but when you add in the large bell and moderate bore size, you have an instrument that will hold it's own on the field. Deep, rich, and resonant this Bb Euphonium provides the depth and quality of sound necessary for todays marching music ensembles. Comes with hard shell deluxe travel case and mouthpiece.
