Hi Manny, A while back I got a new Prana one C trumpet. I couldn't get it to play well for me and I thought the reason was the mouthpiece. I have been playing the trumpet for about a year now with the B flat mouthpiece with pretty good results. In my last lesson my teacher and I worked on not playing high on the pitch and he told me not to use the B flat mouthpiece so I called the factory and ordered another mouthpiece. The trumpet plays so nice now I can't believe it. I have to fight not to play too much because I have a church job in about an hour and a concert tonight. It's nice to finally realize how nicely the trumpet really plays. and it's also nice to know that after about a year of playing the C trumpet the factory is still there to help me.
