I have a trumpet, but unintentionally dropped it. When I started playing, I noticed that the first valve was very sticky. Therefore, I decided to put some oil on it. Despite the oil helping a lot, the valves are still sticking a bit when I push them down, as the key still stays in the valve for a few second before coming up again. It could possibly have a slight dent, but when I opened the valve, I did not see any damage at all. Are there any suggestions? And if it is dented how much would it cost to repair it?
I would wager there is no dent, but the valves aren't quite straight. They have to be straight. Don't know what it will cost to fix, they may have to be replaced.
My valves have had many issues over the past few years. Your problem is either 1. horn is dirty 2. there is a tiny dent (even 1/2mm is enough to stop the valve, happened to me last month). If your horn is dirty, there are plenty of youtube videos on how; it generally involves using water and rising all the gunk out. You could also have too much oil buildup. If there is a dent, don't even try to repair it yourself--it is waaaaay to hard, and you'll ruin the instrument even more. Take it to the store; it should only cost $20-30. I suggest you clean the trumpet first and then try to get it fixed if it is not good.
