Part 1 of a series found while organizing my car. This is a Yamaha custom mouthpiece, apparently popular among trombone players. I received it as a gift and used it a few times on my euphonium. Since my instrument is a Yamaha, I think it suited me well. However, I've left it in the car for several years since I started using my current, larger mouthpiece. It's in excellent condition, except for a slight shank mark. I've gone through another round of brass mouthpieces and gotten rid of them, but I'm still traumatized by receiving one in the past with an unknown origin and being given a bad rating. Therefore, I will wrap it thoroughly in bubble wrap, filling all the gaps, and send it via Takkyubin Compact for secure packaging. There are no dents (this is important). Please take a good look at the photos. I'm not sure about the market price for mouthpieces, so I've looked at others and set a price accordingly. If you think it's too high, please feel free to negotiate a reasonable discount. It's for a large shank. Mouthpiece only, no box.
