Overview
This Bach 1G bass trombone mouthpiece was manufactured during the 1980s, before Bach’s later transition to fully CNC-based production methods. Although produced after the Corporation era, mouthpieces from this period retained many of the traditional manufacturing characteristics associated with earlier Bach examples.
The Bach 1G is the largest conventional bass trombone mouthpiece in the Bach lineup. Its broad rim, deep cup, and open throat were designed for players seeking substantial tonal weight, airflow, power, and low-register presence.

Model Comparison
The Bach 1G has an approximately 28.0 mm inside rim diameter, compared with approximately 27.5 mm for the Bach 1½G and 1¼GM. The additional room and broader proportions can appeal to players who prefer a larger mouthpiece interface.
The 1G also uses a .319-inch throat, the largest throat size in the traditional Bach bass trombone mouthpiece family and the same published throat diameter used by the 1¼GM. This is substantially larger than the .276-inch throat traditionally associated with the Bach 1½G.
Player Perspective
The combination of a broad rim, deep cup, and .319-inch throat gives the Bach 1G an open feel with considerable airflow and tonal depth. It is intended for bass trombonists seeking maximum breadth, weight, and presence rather than the more compact response of smaller traditional models.
Mouthpiece response varies with the player and instrument. The 1G’s unusually large proportions can be highly effective for players whose embouchure and airflow are comfortable with its size, while others may prefer the quicker response of a 1½G or 1¼G-style mouthpiece.
Historical Reference
This 1980s Bach 1G provides a useful reference for players comparing later twentieth-century Bach mouthpiece production with earlier Corporation-era and modern examples. Its dimensions also illustrate the upper end of Bach’s traditional bass trombone mouthpiece range.
