This tenor saxophone mouthpiece is made by Bobby Dukoff and has a tip opening of 8 and D style chamber with a relatively high baffle creating the sound for which Dukoff mouthpieces are known. It has seen extensive playing and has a pretty good tooth mark in the beak. The mark is pretty high so it doesn't bother me but if it bothers you it can be easily filled by a mouthpiece technician. Otherwise it is in excellent condition and plays great. The original ligature is included with the mouthpiece. Let me know if you have any questions. You might ask why I'm selling this great mouthpiece and the other great mouthpieces I have listed on eBay - I no longer play as much as did in the past, and over the years I have accumulated quite a hoard of great mouthpieces that I would now rather see in the hands of someone who will play them. Great mouthpieces like this one don't deserve to spend years and years sitting in a drawer - they need to be on a horn in the hands of someone making great music.
