I received the mouthpiece yesterday and had a chance to play it last night. Overall, I’m floored. It matches my Keilwerth beautifully. I could have searched for years without finding its like. Even my wife had to stop in the middle of her evening routine, something she never does, to comment on the beautiful tone. As I said before, it is still far more subtle than anything I’ve played before and requires greater precision, but it gives so much more in return. The piece you sent can play whisper soft almost effortlessly, but still has significant presence when called for. It is everything I was looking for and more.
