Product Overview
The 99C (like the 100C) falls into a category of sizes that is a bit complicated to sort out due to inconsistencies in Bach rim sizes. It is most similar to a Bach 11C, with a slightly deeper cup.
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.
