We needed to lower the action on this guitar but we were unable to remove any material off the bottom of the saddle because it didn't have enough height above the bridge. We elected to remove material off the bridge and then shape a new saddle made of bone at the correct height for comfortable playability. You can see the amount of height we removed from the bridge in the first photo. The yellowing of the original saddle is from the time it has spent being exposed to the elements. The white unoxidized part of the saddle is the amount of material we removed from the top of the bridge before sanding, shaping, and buffing it back out again.
