well I have an bachelor's degree in queer feminist oral herstories from vassar college, so take it from me, stripping is easy, but it will cost you your self esteem

I'm probably using words wrong but I mean there's 3 philips screws visible here and one hex screw. the hex screw is something you'd touch, but the others, not so much. and there's no "wrong" setting on the hex screw that would cause a creak

anyway. I think it's your saddle. take it off, wipe all the dirt off it, apply a thin layer of heavy all-purpose grease to the clamping points on the rails, then reinstall. I bet that fixes it
