PHC Horn Mouthpiece 24A American Shank - Cup Only I loved the power, core sound, and tone of this mouthpiece, but I've found another one that suits me better. Rather than keeping it stored away, I thought it would be better for someone else to use it, so I'm putting it up for sale. I bought this quite a while ago, but I didn't use it very often, so it's in pretty good condition. It has never been dropped. I will disinfect it before sending it.
