Otto Link 6* - THIS mouthpiece must have been the worst link they released out of the factory because it was terrible the first time I played on it. It was stuffy and very inconsistent when going through the full range of the horn. I picked it up a few days later and tried it again it was a little better but was still very uneven and inconsistent. It is relatively dark mouthpiece not to dark but dark. I was a little disappointed to find that all the rumors were true about links being inconsistent and that you have to try a lot of them to find a good one. I have played on a link on alto for 6 years and I have never had a problem and I love it most people like the link on tenor but I jus tried it on alto and I loved it but that doesn't excuse that sorry excuse for a link that I played on last week. The altissimo range is very hard to play in. Babbitt needs to put some better care into making their mouthpieces. On a scale from 1 to 10 I give it maybe a 4 or 5.
