Screwing Grover (10mm) tuners in place, used straight edge to line them up, drilled small pilot holes first.
I specifically didn’t want retro/vintage tuners on this guitar or cheap ones, as this will be a player. So I opted for the most expensive tuners they have.
Even with my test setup (see further pictures) these tuners stay in tune very well! They have screws on the top of the buttons so you can adjust them to go tight or loose, whatever you prefer.
Grover tuners installed. Funny is to notice how much weight they add to the neck.
