This is a monster jazz bari sax mouthpiece. A Florida vintage Otto Link Super Tone Master Bari sax mouthpiece in as near mint condition as we've seen. It even still has its original lig and cap. This original 6* measures out true at .108", and has a huge, dark sound. The piece takes air incredibly well, and is very easy to control. We found ourselves losing track of time playing this piece because, well it's just a fun piece to play on. Florida vintage Bari pieces are becoming increasingly harder to find, and if you ever have a chance to play on a good one, take advantage of it!!
