This Bach 12C small-shank trombone mouthpiece is in open-box condition—literally brand-new, still in the factory box, and never played. The 12C features a medium-depth cup, 24.50 mm diameter, and a medium-wide rim, making it one of the most balanced and comfortable beginner-friendly models. Its approachable size and classic Bach response make it ideal for elementary-age players whose facial structure and embouchure are still developing—perfect for building solid tone and technique from the start.
New Bach 12C mouthpieces typically retail from $124 MSRP down to sale prices around $85. As a genuine open-box piece, this one gives you that like-new quality for noticeably less. Perfect for new players—full factory condition, great for starting out, with savings over MSRP.
