Product Overview
The 100C falls into a category of sizes that is a bit complicated to sort out due to inconsistencies in Bach rim sizes and overlap in the dimensions of mouthpieces in this range. It is most similar to a Bach 11C, with a slightly larger diameter. It is also close to the Bach 6.75C.
The updated G3 design is similar to the Gen 2 line, but the top and bottom rim of the G3 each have a slightly different shape. The bite on the rim is also slightly softer. Most players prefer the wider rim at the top and the orientation dot at the bottom, but the mouthpiece can be pllayed in either orientation.
