I own a 1913 Conn Eb "Monster" 3 piston valve tuba that I would like to add a 4th to it, and I know all of you tubists out there will recommend adding a piston valve, but how about a rotary valve? Has anyone done such a project on a tuba, and if so, how did it work out? One last question....which would cost more, a rotary or piston valve? Thanks.
