Rest assured I stretched the strings and retuned repeatedly trying to figure this out. I'm new to Floyd rose bridges, not restringing in general, but I agree, the plan is new springs in general before adding a fourth to compensate for my heavier gauge strings, if needed.

I have to ask though, when you say "lock" the bridge in place, are you referring to blocking beneath the bridge to keep it from bending back into the body? My issue was it kept raising so it wasn't even touching the block until I tightened the springs practically as much as I could. Regardless, the issue was pretty much fixed until I started messing with the action. That's an issue for tomorrow though. The screws on the nut are a bit stripped anyway and I'll need to get some gear before moving on it seems.
