I'm new here. I'll say that to start off. I play on a Yamaha YTS52, which I love. ^_^. With it I play on an old Otto Link 5 metal amd I've personally opened the tip to what I can say is about a 5*-6. The only problem that I'm having is that I can't figure out what modelis or era the mouthpiece is from. Is there any way to tell the difference between a florida and a new york, or any other model for that matter? I'll say that it has "super" tonemaster engraved on the neck, U.S.A on the underside. That might be on a lot of Otto links, but that 's all I really have to work with on pinpointing it's era. can anyone help me?
