The nut was something it benefited from quite a bit, yeah. Mainly because I started using crazy guage strings in very low tunings: its easier to replace it altogether and get the right string hight (a little tiny fraction of a mm higher for heavy strings) than it is to widen a groove without deepening it.
The tuners didnt need changing for anything but bragging rights :lol: I was swapping out a set that did need changing and thought "Screw it".
I couldve left 10s on and just changed the pickups, it would be the same difference.
But point taken!
