This Vincent Bach Corporation-era 1½G bass trombone mouthpiece has been sold and is now part of our Archive of Sold Mouthpieces, shown here as a historical reference for players and collectors researching vintage Bach models and values.
✦ Historical Perspective
This Bach Corporation-era 1½G mouthpiece was manufactured in Elkhart between approximately 1963 and the late 1970s and bears the classic “Corporation” stamp. Mouthpieces from this period were produced using traditional lathe methods and are still valued today for their consistency, feel, and tonal balance.
The Bach 1½G is one of the most important bass trombone mouthpiece sizes ever produced. For decades it has been considered the benchmark for an all-around bass trombone setup, offering the balance of cup depth, rim comfort, and backbore efficiency that works across orchestral, wind ensemble, jazz, and commercial playing.
Many players start their bass trombone journey on a 1½G and continue using it for years because it provides a centered tone, strong low-register support, and reliable response without feeling overly large or inefficient. Even today, newer boutique designs are often compared directly against the Bach 1½G standard.
Vintage Corporation-era examples like this one are especially interesting to players researching historical Bach manufacturing and the evolution of trombone mouthpiece design.
✦ Player Perspective
For most bass trombonists, the 1½G sits in the “just right” category — large enough to produce a full orchestral bass sound, yet flexible and efficient for everyday playing.
It pairs well with both single-valve and double-valve bass trombones and blends naturally in section playing. Many teachers still recommend this size as a starting point for developing bass trombonists because it supports proper airflow without forcing excessive mouthpiece size too early.
Vintage Bach pieces often show subtle differences in feel compared to modern production, and many players enjoy exploring those differences to find their personal match.
