Hi there- I am the mom of a 14 year old tenor sax player. I am a music teacher myself but a string player so I'm a little lost when it comes to wind instruments. So My son has been playing for 4 years right now and he is quite good having made it into honor bands- symphonic and jazz. I've been looking into buying him a new saxophone since he is still playing his student level yamaha but until I get the money for that I was wanting to get him a new mouthpiece since I have heard that makes a big difference as well. His teacher suggested a Selmer C star. She is a clarinet player by experience so I trust her when it comes to reed instruments but I am wondering if any of you out there have found a comparable mouthpiece for less money. I also had found a website for Kessler music out of Vegas that makes custom mouthpieces for less. Does anybody out there have any experience with Kessler's and are they worth it? Also, I am guessing from the stuff I have seen that plastic is mainly a student level material whereas I would be looking for a hard rubber for an upper level player- and metal for jazz? I know just the basics and trying to learn to do the best for my son. He is really talented and I want him to have an instrument that does him justice. Any information is appreciated!
