Removing the Bounce in Your Low C Key::
To help remove the bounce in the low C key of the saxophone. Move the spring out
under the arm of the key. Cut as small slot in the key not to deep. Adjust the spring and place it in the slot.
This changes the pivot point of the spring and does not allow the key to bounce as much.
