I have the usual symptoms of a truss rud which is too tight, the frets buzzing from open to the 2nd or 3rd fret. I went to loosen it off a bit, and it feels way too loose, if i loosen it any more there is no resistance (it feels as though the screw is completely out). I tried tightening it just to make sure it wasn't wrecked somehow and it will still tighten. What's going on inside my truss rod cover?

I'm nervous you have hosed your guitar. It doesnt take much turning to loosen/tighten a truss rod. You should have measured the relief in your neck, because even though there is fret buzz that does not automatically mean your truss rod needed adjusted.

I always make small adjustments, I turned it less than 1/8 of a turn when it "came loose".
