The cast piece involves a stirrup (20) whose outer wall (21) is formed in uniform wall thickness, an inner guide bend (22), and a flange plate (30), forming a one-piece cast piece or two one-piece, identical cast parts. The inner cross-section of the stirrup is round and from the cross-section of the aperture of the side bore (11) continually enlarges to the cross-section of the aperture of the bass tube bore (12) of the instrument.
