Hey, I'm new here and after using this site for information about mouthpieces I decided join. I also decided to upgrade from my old Bach 3C to a new Monette STC-1 B6. I read that the B6 was most similar to the 3C. However, I still have some questions. What is the difference like b/t these two mouthpieces? Is it really that hard to get used to a monette? Will this work with my Olds trumpet? Thanks for the help!
