my silver hüttl trombone (which went trough a massive undenting process after I bought it for very little money) sucks all my energy and puts it in bell vibrations one can feel and hear clearly when playing it. This behavior happens just in a very specific frequency spot on a well tuned c. This is just like when one sings in resonance with a good wine glass. It is a little annoying because it makes this tone very unresponsive. Since I use this instrument just for marching purposes I could live with it but I would rather not. So if you have some low effort tip to stop the universe sucking my energy on c please give it to me - thanks (: I tried damping it with a tshirt wrapped around the bell and this works but I feel like this looks uncool and makes the trombone even more front heavy than it is already.
) or try something else. There are various sorts of (smooth flexible plastic) shelf/drawer liners out of which it would be pretty easy to make something (even with using some self-adhesive Velcro strips on the wrap so you could put it on and take it off). The major drug stores carry the self-adhesive bandage or you can get it from Amazon.
