HAHAHAHAHAHAHA!!! TRICKG My first "professional" horn was a Bach Strad 37 bell. Used it for marching band. Well oddly once it started getting really damp here in Florida during the fall, that it wouldn't perform well anymore. My high c's would come out horribly. The horn wouldn't respond when it was very humid outside. It caused me an embarrassment in front of a packed stadium. i went to play my solo that went up to a high E and it wouldn't play. I was so disappointed. When I got home that night the house humidity level was very very low. I played my solo and the horn played amazing. I went out side my house and played a little bit and then tried my solo again. Guess what, it wouldn't respond. Solution to the problem: Went and convinced my dad it was time for a new horn. Purchased a Schilke X3. With two weeks worth of heavy duty slurs and long tone exercises I adapted to the huge bore of the X3. Went to districts and played my solo very well with my new Schilke. I love Schilke. I still have my Bach, but I won't be using that outside. I'd like to save myself some embarrassment .
