I bite right through them- but I guess that says it all!
I did this myself for a long time, I love the airy ala Getz type tone produced with the double embouchure, but 15 yrs ago I copped my first Guardala tenor mpc, and while striving for altissimo strength I found I needed my teeth for support on the mpc..No here. I play with a double embouchure, so the only thing that could benefit from some protection would be my top lip, after 4-5 hours of plaing.
Try using two. The thick ones are super squishy. I can't stand them. I'll bite through them instantly.Don't knwo if I am weird or what but I can't play (metal) mouthpiece only with those thin clear patches. It just resonates in my brain and I have to stop immediately. I am using those thick black vandoren patches.
