Re: Sax Mouthpiece
You don't mention if you prefer HR or metal, but since you are mainly a clarinet player, I will assume that you are looking for hard rubber. Here are a couple of reviews of some good jazz tenor mouthpieces that are on Steve Neff's website.
They are both closer to the $200 price point.
Also, I was also originally a clarinet player who then picked up the alto and tenor saxes. From my experience, you can probably get by on alto with a tighter embouchure, but you really need to learn to roll over less lip and relax your embouchure on tenor. That longer tenor reed really needs to vibrate freely with no damping from the lip or pinching from embouchure in order to get full and lush sounding low notes.
Good luck, and have fun in jazz band!
