Magnificent step-up instrument for the committed student. The 1020 Series Euphonium offers top design in a non-compensating instrument. It features a traditional 3+1 valve design with three top action valves and an angled left hand 4th valve to eliminate the use of the right hand pinky finger. This design is very comfortable to hold and play. The .570 inch bore offers a warm, rich euphonium sound perfect for band and solo work.
