The King K30SP hybrid euphonium offers deep rich voicing to compliment the balance of any marching organization. It combines the sound and response of a concert euphonium with the size and balance of a marching baritone. Allows for a full lower register and a unique voicing on the field that baritones cannot offer. Nickel plated pistons provide smooth, quick action and unmatched durability. The heavy duty marching case is designed to be stackable to minimize space requirements.
