1 mike77 1 week ago Anyone with a G5422 tried the Grover 533 locking tuners? The screw holes are 1mm off but I can live with that. The Grover tuning ratio is 1:15 where the stock tuners are 1:18. I checked the Grover's spec sheet and measured the stock tuners. I will have to fill and redrill the screw holes but that's minor. Any thought would be helpful.
