Call Winslow Ligatures at 608.241.1124. If he does not have one for your mouthpiece already made, he can make one for your mouthpiece. These are great ligatures. Incredibly free blowing. I can play things on my sax with this ligature on the mouthpiece that I cannot with a different lig on the same mouthpiece and reed. Give him a call. I think you will like his ligatures a lot.
