Just got piston valves lapped, and connection points re-soldered for more resonance. Big Mouth Brass tubas have a dependent 5 valve rotary system. Where the main 4 valves are piston operated, the 5th valve is operated using a tension-band system that many tubists prefer to the typical rotary valve. Comes with a mouthpiece and a soft case.
