Not yet available. My idea is a carbon stand that suits any tuba, regardless size. Bell will be up. The instrument will be very well balanced in the stand, but at the same time is will be easy to put it into the stand or take it out. It will probably weigh 1 kg or 2 pounds, and will be transportable inside the bell of the instrument.
Of course a tuba is not a baritone saxophone, but when you look at the video below, especially at the bari sax section, you might get an idea of what I have in my head, but didn’t take the time yet to get it out of my head and make the first prototype.
Interested in the idea? Let me know.
