Hello. I recently set the neck on my electric guitar which was easy, I then set the saddle height (Floyd rose style bridge). Im having trouble setting the string height anywhere near as low as they were before and every time I lower or raise them the dull strings vary a lot and don't know why. There's more than a .25 mm gap from the straight edge to the 8th fret but also most of the dull notes are toward the nut. Also the thing that I cannot figure out is some of the dull strings are definitely not touching any fret or anything at all, the dullness must be the nut or bridge! The floyd rose copy bridge has two raising/lowering screws but as I say I can't get the action anywhere near what it was before. Any ideas people?
