I purchased these to fit to a PRS SE Custom 24, which has a tremolo, and no locking heads, and therefore some tuning instability.
These installed into the original headstock holes perfectly - no drilling required. Took me 30 minutes and I'm no expert.
Stringing the guitar is now really easy, though the included instruction are unclear on how to actually do it. Simply line up the hole with the fingerboard, thread the string straight through, and turn the tuning key until it locks. Simple, when you know how!
The guitar now holds its tuning perfectly. It really is much, much better. These are highly recommended. They also look great on this specific guitar - they are spot on.
Good locking tuners - locks automatically when turning the tuning heads
Good quality and by my opinion a good replacement for those standard Groover tuners that comes on a lot brands like ESP ltd series if you need better tuning stability.
By my opinion, there are only one thing to consider when you want to buy locking tuners, at least for what regards the functionality. Are you comfortable with locking the strings your self, as some locking tuners acquires or are you comfortable with having that done automatically as described in subject?
In the end I think that it is the main question you should ask your self before buying. With locking tuners it should be easy to change the strings, and it is with these ones, but I actually prefer the other types of locking tuners.
