Happy New Year! I'm was looking into a used Dynasty 4 valve, BBb Sousaphone. I noticed there is tubing that wraps around the main tubing, which I think goes with the fourth valve. Has anyone played a Dynasty Sousa 4 valve? How is it?

I have a used Dynasty 4-valve sousaphone (see my pic to the right). On mine, the fourth valve plays remarkably flat. I bought it anyway because it was a good deal, but it turns out I don't use the fourth valve much, so it's just extra weight to carry around. One of these days I'm going to look into having that issue fixed. Otherwise, it's a good horn with a great big sound.

Also ... DyNASTY is no longer making instruments... might be difficult to get serviced.
