With marching band over about a week ago, and concert season starting, I put my old trumpet to rest, and took out my concert trumpet, A Bach Stradivarius. Now, I have owned it for about maybe a year and a half and my warranty is all finished up. The problem with it is the silver of the some parts is wearing and peeling off and it looks terrible, and on top of that my tunning slide, the front one is completely stuck. Anything I can do myself or will I have to send it to a music shop, and if so, how much will that cost. All comments appreciated.
