I purchased this on Mercari at the end of September 2025. I liked that the shank is copper, and it does have a warm sound. I've played it for about two hours total with a patch, but I'm selling it to declutter. I think the tip opening is around 8 to 8☆, similar to a Link rubber mouthpiece. I'm open to a small discount, so please contact me. Here's the previous owner's description: Tenor saxophone mouthpiece, NYC copper shank (2.70mm). Purchased new in December 2023. I had a craftsman specially make this with a copper shank. It's practically unused, only tried out. I played it for about 30 minutes with a patch. I'm selling it because I'm going to use a similar one with a different opening. Compared to the standard model, it's said to have a thicker, warmer sound.
