So I'm not a Super Chopper... yet... Am I going to become one? Maybe??? I have the DVD and have done some experimenting... I'm not sure if it's for me or not yet. That being said, I have a few thoughts... First of all, go to the trumpetherald site... there is a whole forum dedicated to Callet "stuff" there... with a lot of good info. Second... since I visited Kyle (Jerry's "right hand man" in business) a few months ago to buy a horn from him I have been using Jerry's SC 4 mouthpiece and REALLY like it!!! BUT... I'm not sure if I'd try and switch mouthpieces AND embouchure all at once. What Mouthpiece are you playing now? What style(s) of playing do you do? Just some thoughts. Good Luck!!!
