Vincent Bach 5GL Trombone Mouthpiece Large Shank (Bach 341-5GL)

Vincent Bach 5GL Large Shank Trombone Mouthpiece – New

The Bach 5GL is an older variation of the 5G, designed with a shallower cup and a slightly larger throat to facilitate easier access to the upper range while still maintaining warmth and core. Compared to the standard 5G, the 5GL offers a freer blow and more flexibility, making it a strong choice for tenor trombonists who need both depth and upper-register clarity.

With a 25.50 mm medium cup, .276″ throat, and the #429 backbore, this model produces a resonant tone with excellent projection. The medium-wide, deep semi-flat rim provides stability and comfort for extended playing.
