I'll have to check on pressing behind the nut. If I bend a string, sometimes it stays sharp or flat, other times, it goes flat. I have been backfiling to keep that angle in place, though I'm also being really careful to try not to take anything out of the bottom of the groove. Just the sides. I'm really hoping not to need to modify my new guitar for it to be playable.
