I decided to purchase this mouthpiece upon the recommendation of my teacher, who plays an actual vintage Otto Link 8*. This mouthpiece bears an uncanny resemblance to the original, and produces a round fat dark tone, which is easily controllable to suit any situation. It brought my Yanagisawa to life, and the ease of the altissimo register was immediately apparent. I am a professional saxophone player and I now play this mouthpiece full time, in conjunction with the matching Rovner ligature, which I would highly recommend. Initially I found it harder to play than other mouthpieces I had encountered before, but that's just because it requires a bit more air, which I got used to in a couple of weeks.I would highly recommend this mouthpiece to anyone looking for a good all round mouthpiece; it definitely bears the more vintage feel as compared to the standard Otto Links.
