I just got the mouthpiece yesterday after about a week of searching for the right mouthpiece. WOW! What a difference! I’m a high school student in a jazz band and sax quartet and have been looking for this sound since I started playing, round, rich, big, and above all, easy to play even with worn out, several month old reeds. I tried it out in a music store against 3 others which are now irrelevant – I was sold from my first note! The HR* is not only a mouthpiece, it is a masterpiece!
