103G
The 103G is similar in size and playing characteristics to a Bach 4G. It is a popular orchestral mouthpiece for those with a strong embouchure who want a big sound. It is also an excellent euphonium mouthpiece with the large shank or baritone mouthpiece with the small shank option. The 103G has an ID of 1.03 inches and a .280 throat.
103GS
The 103GS combines the ID of a 103G (similar to a Bach 4G, Schilke 52, DE 103, Yamaha 52, Denis Wick 4AL) with a slightly shallower GS cup, similar to a Bach 5GS. It is an excellent choice for a player who wants a larger diameter than the 5GS without giving up the greater brilliance, projection, and ease of upper register provided by the GS cup.
