Introducing the Centennial Bach Trombones

🎵 Unlock New Possibilities with KGUMUSIC Trombone Mouthpiece Adapte Trombone mouthpieces come in two standard types – thick and thin leg. Traditionally, these types were not interchangeable, which meant that instruments designed for thick-leg mouthpieces could only use mouthpieces with thick legs. But now, thanks to our KGUMUSIC Adapter, you can break free from this limitation! Our adapter allows you to use a mouthpiece with a thin leg on a trombone designed for thick-leg mouthpieces. . . . . .
