I've been getting back into playing trumpet. I'm still using a 5C mouthpiece from years ago when I played in concert band in school. I also played lead in a jazz ensemble and marching band and my band director would not allow us to switch mouthpieces. Some people would sneak a Shilke 14A4A, but they were confiscated. I was made to believe that they would ruin my playing. I still have pretty good range on the 5C, and it sounds really pretty, but I need something with more of an edge, and something that won't wear me out so fast when I'm playing the high stuff. I'd like to start playing jazz/blues/R&B. I need help picking a new mouthpiece. There are so many to choose from. Anybody got any advice?
