I bought a Bb trumpet from Ebay (I know, probably not the best idea) and when it arrived it was really good, except the valves. They wouldn't go down (or up) really well, so I oiled them, and it helped, but it still won't go up properly (it might go up halfway, then suddenly stop, then go up slowly). The valves sound like they're scraping the side a little, and valve oil doesn't do much good. I don't know what brand it is, so don't ask. Another thing, is there such a thing as over-oiling?
There's a good chance that the casein is bent from being dropped. Or the valve guides are wore out. Hopefully the later because it's the least expensive. New ones can be ordered. If the casing is bent maybe a repair tech can do some straightening or possibe have the casing re-honed.
The trumpet has to have the valve holes lined up with the trumpet air passageways in order to have your air proceed by the trumpet and characteristic a sound produce. Your valve must have an computerized locking mechanism (the small piece of plastic close to the spring). now and again this receives worn down, and the valve gained't line up wisely. To treatment this, you should locate the starting up turning position of the valve and tighten the valve starting up there. i imagine that is ninety degrees to the left at the same time as the bigger plastic piece is dealing with the mouthpiece aspect of the trumpet.
First okorder or your local music store may have it or order it for you. The DVD is 4hours of great trumpet educational material and one chapter is about the care and maintenance of your trumpet.The video will show clearly needs to be done to get your horn in workable condition.
Sell it on Ebay. Now go to a music shop and play one before you buy it. Lesson learned. I bought a pocket trumpet that way. Same problem - took it to a shop, never go the valves to work right. Eventually pitched it. I'll never do that again.
When dealing with complex and artistic things such as musical instruments, ALWAYS buy form where you can trust, and preferably from where you can test the item out.
