I just got a second hand Esp with a floyd rose on it. It has Seymour Duncans in it, so i loosened all the strings to take the humbuckers out to see what model they were.

So anyway, i tighten the strings back up and they all now have fret buzz (on open notes) and the Floyd is right down in its cavity.

How do i fix this so it goes back to the way it was?
loosen the strings, lift the tremolo up a bit, and make sure its sitting correctly on the pegs on either side of it, nearest the bridge humbucker
