So, I signed up to get on the list for the Harrelson Bravura demo horn. It came in this past Saturday. I really like the way this horn plays, the tone is much darker and colorful than my Yamaha, everyone has noticed that right off the bat. It plays much easier and doesn't require as much effort to project well. The only problem I have is that it is definitely harder for me to play in my upper register, which should definitely not be the case. I do notice that the mark on my mouthpiece from where it sits in my Yamaha sticks out about .3 mm. Could that be the issue? It came w. 4 diff lead pipes: 4, 5, 6, and 9. I can't tell that the 3 diff. weights of bottom valve caps make much difference, and there is a semi round tuning slide that should be here in the mail today. So I still have some experimentation to do, but just wanted to get opinions to see what it could be. I normally play on a YTR2335 if that helps any at all.
