So I have had my trumpet for 2 years now. It's a black Nickel plated Cannonball.... 725 (i think). I bought it used, the previous owner played it for about a year then left it in his closet for I think another year. something like that before I took it, so it is fairly new. What I am starting to notice though is that the lacquer is starting to wear off noticeably around where I hold it. inside the ring, on the valve holder thing. I also noticed that it plays sharp, I have to pull out an at least an inch for it to play in tune. I have a strong reason to believe that the paint job is causing the tuning problem, since my friend did talk to the owner of cannonball about it, and he said that that might be the issue. And I was considering getting my horn relacquered because of these two problems. I know that a lot of older horns get this... but should I? Im probably gonna get a standard lacquer finish on it or just strip the lacquer and leave it raw.
P.S. I am NOT considering getting a new horn. I like my horn!
