What is the difference between these two mouthpieces? I have a student who played an S80 and loved it, but wants to buy a S90 because it is cheaper... -.-... anyway, I would appreciate some opinions on these two mouthpieces. Thank you very much 
I agree with this. I use to use an S80 C* for a few years and my Professor let me try out his S90 (his main mouthpiece). It had just a bit more darker...fuller tone to it compared to the S80...thejoyofsax said:Looking down into my S80 and S90 side by side, they both have square chambers. The Selmer Larry Teal has the round chamber. The Soloist model has the arch, I believe.
The only visual difference on the outside is that the S90 has a longer table. If I were to speculate, I'd say that the S90 has a larger chamber than the S80. I get a much more full, deep sound especially in the low register when I play it. Listeners noticed a big difference between the two, even after a few notes. I highly recommend the S90, even after playing the S80 for the last five years.
Actually, I have to say that the 80 wins that round. If my 90 has been sitting a couple of minutes (say I explain something to a student and then go to play an example phrase for them) it takes a second for it to kick back in again. Once you get it to peak moisture it's fine, but I might be nervous playing it for an orchestral gig, let's say. While that could be more of an "old reed" issue, it seems like the one major drawback I've found.gary said:How's the response/reaction to articulation in the S90 vs S80? Thanks.
