Vincent Bach 5GS trombone/euphonium mouthpiece. This was purchased at a Yamaha store and was gold-plated. It has been used for several years, so there are some insertion marks on the shank. However, there are no dents on the rim or shank, so I don't think it will affect your playing. The photos may look uneven in color due to my poor photography skills, but the gold plating is still in good condition with few scratches except for the shank. The photos with more reflection are closer to the actual appearance. Although the colors look different, they are of the same item. Please check the photos and description carefully before purchasing as this is a used item. *Price reduced slightly. I do not plan to lower the price further, so please refrain from price negotiations.
