"Dedicated to the preservation of the funkiest instrument known to man."
Locate the two screws on the right side of the keyboard assembly and remove.
In the center of the keyboard at the top, is a small brace located beneath the keys. Remove the screw in the center (its removed in the photo).
Grasp the keyboard assembly by the metal bars and lift it off the 4 studs.
You can lift it off with two hands, I just lifted each side for photo purposes.
Congratulations! You now have direct access to the strings and the keyboard assembly.
