Also, I believe the common consensus from folks here is that material of Mouthpieces makes no difference. But that should probably be in its own relevant thread (or any of the 1000s of previous ones)
I think the consensus is that material per se doesn't make an acoustic difference (i.e., one that is audible, in itself, to a listener).When it comes to hard rubber versus plastic nobody in the world can tell me they feel the same to my top teeth and palate and head while I play, even if they think they sound identical - which I don’t. <smile>
There are many different plastics (of which hard rubber is one type) and they can feel quite a bit different to the player. For me, lighter plastics feel very unpleasantly "buzzy", but plastics that have roughly the same density and hardness as hard rubber feel virtually indistinguishable.
