Okay, my guitar is currently setup for 10s, but I'm switching to 11s. The neck has a little bow in it when sighting down the fretboard, but I have been told that's normal and shouldn't be flat. Anyways, should I have to adjust my truss rod for switching from 10s to 11s? If so, how do I adjust it? I can't seem to fit a screwdriver into that little hole in the pickguard, I guess I'd have to take the pickguard off. Which direction does the neck bend when I tighten the truss rod? When loosening? A detailed description on how to adjust it correctly for 11s would be much appreciated. Oh, and I don't have a feeler gauge right now, I can get one tomorrow or the day after tomorrow..
