I'm both.Have you been a lead player for "many years", or are you a high school kid?
I think there are too many variables to be able to tell if there's something wrong with the Getzen. Have a teacher or a good player A/B them and give you an honest opinion. If they feel the same as you then there may be something wrong with the horn.
If not, maybe the mouthpiece horn combo isn't working.
If you like the way you sound on the Jupiter and it plays better thna the Getzen, I'd say have someone fix the valves and make the Jupiter your primary horn...
And thanks i'll see about that
