Adjusting the cello on the harness
Undo the two locknuts on the socket arms
just enough to allow movement of the cello.
Adjust the cello to the desired position.
Lock tight the locknuts on the socket arms.
When the arms locknut faces upward you will have greater side-to-side adjustment flexibility.
When the arms locknut faces sideways you will have greater up and down adjustment flexibility.
