Thank you for viewing. This is a VINCENT BACH 5GS trombone/euphonium mouthpiece for small shank, with a gold-plated rim. Since it's not a post-application plating, there's less peeling or degradation of the gold plating. I opened it once and used it, but it didn't suit me, so I'm putting it up for sale. (Seller purchased: early June 2025) I haven't found any scratches, stains, or dents in the areas I checked. If you have any questions, I will answer them to the best of my ability, so please feel free to ask. Returns are not accepted, so please be careful about the size.
