A little history first. I've always wanted to learn how to play the sax since grade school, but it scared the crap out of me. I took up the trumpet instead, not realizing that I had to learn all the notes using three keys, I was in the second grade. Played through H. S. Fast forward, I'm now 64. My grandson is 11 and guess what, he's taking sax lessons. Now this is my last chance at the sax and a great way to bond with him. So I bought a Yamaha YAS 21 alto, it's a nice piece too! I actually was able to blow a couple of notes too. Now here's my question, (at last), even though it came with a mouthpiece it's used. I'd like to know is there a mouthpiece that is equivalent to the 4c that is either hard rubber or metal that's decent and will last?
