Hi Ted, this is Ralph Caccese from Delaware. I spoke with you on the phone last week and ordered a #4 cornet mouthpiece. I just got it today and have been playing with it for the past hour. I just wanted to say this is one terrific mouthpiece! The best I’ve tried. I’m not a great player but I found it far better than the Wick RW3B and 4B I have been using. The rim is much more comfortable; it feels less sharp. The sound is incredible. When I first looked at the mpc I thought I would have trouble hitting high notes because the cup appeared so deep. I found just the opposite to be true. It’s easier for me to get up there, and when I do, it sounds much better than before; in fact in tune for a change. And the low register is thick, mellow and warm. I’m using a Getzen 3850 which I recently bought. It’s a great horn, but the mpc has made all the difference . Thanks.
