Really good at sounding like real vintage otto links. Im very very please. From what Ive heard it can be slightly hit or miss with some people getting amazing mouthpieces and some not but i really feel like I got the best mouthpiece Ive ever tried. Paired with a 4 selmer jazz reed, H forestone, 3.5 Vandoren blue or a daddario reserve 4 and with my rovner dark 2r ligature ive i feel like my sax is allowing me to play as dark and mellow as I am capable of doing with my level. Maybe one day my needs will change but for right now this was my perfect mouthpiece.
