Hello Everyone. This is my first post here and the title is pretty self explanatory. I have been playing for about a year on an Olds Ambassador. The horn is in pretty poor condition with many dents throughout and whatnot. I have not played a "pro" or any such trumpet before so I have no real reference to what a trumpet could and should be. Anyways I have heard of how great the Olds Ambassadors are but I still feel I might be missing out on something. I have limited budget(around 300 dollars) and don't know if trumpets that price will be much better. So, how do I know when It's time for a new instrument? Thanks for the help!
