What is the difference between an Inline and Offset G?
The double G key that you play with the third finger of your left hand is the key we are talking about. It can be placed on the same steel rod as the other keys (in line) or on a smaller steel rod of its own, closer to the hand (Offset). There are different opinions on this feature, many professionals & teachers prefer inline G, but an offset G allows for a more comfortable hand position and can lead to better hand health over the years of playing.
