When i started playing the sax i didn’t use a patch and the tone was great, however my teeth kept sliding on the mouthpiece, so i played with a rubber patch and noticed straight away it dulled the pitch, however i got used to the sound.
Then i wore out the patch, and i couldn’t get hold of another patch, so i made one out of an old cane reed to the exact shape and size. The pitch was far superior than rubber – imagine an acoustic guitar made out of rubber that sounds horrible, to me that’s what rubber does it dampens vibrations. Wood or fibre vibrate better than rubber.
the only reason i moved to fibre is it’s harder to bite through than wood.
