These are CRAP!!! They don't even fit in a gibson's headstock without routing!!! And after you make the holes bigger, they only have one screw that doesn't hold them in place. So the whole Tuner moves with your string. You can push the tuner sideways and go up a whole note... without turning the button!!! I'm mad!!!

Well I got these because my niece knocked my Gibson SG down and broke one of the tuners, Luckily thats all that broke. when I finaly got these I put them in myself, and they worked out great, Nothing better. Never goes out of tune, Never. These worked for me and I hope they work for you. Good Luck.

I bought these at my local guitar center recently and installed them on my epi les paul. They fit perfectly and no modifications or drilling was needed. I replaced my old ones because one of the old ones bent and spun freely and didnt hold a tune. I didnt realize that these tuners would be better. The ratio is excellent, and they have a bit more resistance so they stay in tune better and make it easier to find that sweet spot in perfect tune. As for looks, they look great and look much better than the stock epi ones. The reason they got a four for features is because I wish they could come with a locking feature. Other than that they are perfect.

If your guitar suffers tuning problems, put these in NOW. I put these in my Epi and am very pleased. They do go out of tune if bumped, but other than that, they are just fine.

i bought these a few days ago from my local guitar shop, and must say they're killer. they hold my Les Paul kit/copy (i put it together) in tune really well. i gave them a lower features rating cause they don't have some crazy gear ratio, butt they fine tune pretty well. they're beautiful tuners, but i was surpirsed that the back of them says "GROVER" instead of "GIBSON". i was pleased to Grover tuners. they're heavy though, and pretty chunky, substantially more than my previous ones. good on a guitar with a good weight, but maybe not on an SG.
