So I've been getting into jazz, and I play lead every once a while. I currently play a 3C My band director (a trumpet player) suggested that I get a jazz mouthpiece for more zip. My private teacher thought it was ok as long as I used it only for jazz. I tried out a lot of mouthpieces, including Schilkes, Yamahas, Kanstuls, and every piece from a set of mouthpieces provided specifically for dealers (I forget which company). Anyway, none of them really made a difference in sound, ease, range, or endurance, so I basically forgot about it. I know there are a lot more out there, but I was beginning to be discouraged. I then stumbled upon Al Cass mouthpieces. These are pretty much a no risk investment, as you can sell them for the same price or more if you don't like them. After doing some research and studying my embouchure, I found that I fall under the category of having an "efficient" buzz. I wanted no bite, so I went for an Al Cass 2-28, 2 meaning medium rim diameter and 28 meaning a size 28 throat (I've always preffered resistance anyways). I wasn't really sure if the hype was justified; were people just imagining things? Well today I got my mouthpiece, and I was so impressed that I made a recording so that you can very clearly hear the difference. I've recorded 4 takes of the West End Blues Cadenza, one after another, first try, unedited so as to reduce the possibility of a fluke attempt on the Al Cass. The first and third takes are on my 3C, and the second and fourth are on the Al Cass. These are done one after as fast as possible to reduce any other variables. Here you go (please listen to all the takes): YouTube - Al Cass West End Blues The third take was so tough on my 3C that I basically just gave up, missing pretty much everything after. The cool thing is that I use considerably less pressure on the Al Cass. In fact, I use almost no pressure. This was not intended to be an Al Casses are the best for everyone thread, even though I do believe that Mr. Cass was on to something and that his pieces are worth a try. It's just to show that it's important to find the "right" mouthpiece, whatever that may be, and it's worth the effort. I've always struggled with getting a big sound from g# above the staff, and with the right mouthpiece, it's not very hard at all, and there is no sacrifice to the lower register. The sound is better, there is ease of play. Maybe you shouldn't go looking for the "magic" mouthpiece to solve your problems, but you should try to find one that fits you.
