Hey guys, I'm trying to sell my Bach strad, but it's got a few problems. It was my marching horn, and no gloves during practice made the sweat eat away at the lacquer, so around the valves it has been worn away. It also has a possible bent valve/valve casing. it really doesnt move slow but if you push it down all the way it will stick at the very bottom, and is pretty hard to pull back up. like i've almost considered using pliers a few times. Any Ideas on what I should do? I'd like to do it myself if it's possible, cause straight music isn't too cheap or quick with their cleaning or repairs. FYI it is a model 43 Bach Strad with the "light weight" star on the bell. Thanks.
