"Bach Commercial Mouthpiece" Two new "commercial mouthpiece" models are now available: the shallow "Shallow Cup" and the V-cup "Modified V Cup". All models feature a standard #27 (.144) throat and a flat rim that has been comfortably modified for commercial use. The body design combines the comfortable feel of the Bach Standard model with the excellent projection of the Bach Megatone. A new option has emerged from the back.
