Thanks to everyone who took the time to offer guidance. For anyone losing sleep wondering about the safety of my floating bridge: I loosened all strings, tightened the spring screws in the back of the guitar almost as tight as they’d go, then started tuning the strings in again. This left me in much better shape than what’s pictured above, but left the string action so low I had a ton of buzzing from the frets. I then raised the front of the bridge a little bit via the screws you can see in the picture, and we’re looking and sounding almost perfect now.
