I just played it for 30 minutes (I have to go to work now). It’s even better than I expected. It plays the high notes better than I’ve ever experienced on soprano. The whole range is beautiful. Very consistent from high to low notes. It plays very warm and I get plenty of volume with it also. I plan on doing some recording soon. I will send you videos when I do. I hadn’t planned on recording soprano, but now I want to with this mouthpiece Thanks for making this amazing mouthpiece.
