My SE locking tuners finally arrived and I installed them today, only running into 1 minor issue. The supplied screws are too small (diameter, not length) for my 2017 MIK SE Santana. Maybe not an issue for guitars from Indonesia? I was able to just reuse the ones that came out of the stock tuners. Restringing was quite a bit faster, and the unplated brass shafts look awesome. Shame about the hardware. The exact same ratio as the stock ones too so no unexpected change there. 18:1 Here is an image of the two machine heads and you will notice the screw size difference.
