No. I don't know if the PPT piece has standard dimensions. But I know that my optimum ligatures fits every HR piece I have for soprano, alto and tenor I have, and for a lot of different mouthpiece brands. For my baritone piece, I use a HR tenor optimum ligature. I also have a optimum for tenor that fits most of my metal pieces. What I meant, was that you have to check that you get the right size ;-)Are you saying it works with a PPT?
