Bought these to replace the Grover tuners on my Epiphone Korina Flying V. The screw holes were in the same place so they fitted perfectly. They've improved the tuning stability of the V incredibly, it now holds tuning for far longer than the original tuners on the guitar, and stringing the V up was so easy.
I highly recommend these to anyone looking to upgrade their guitar!
I ordered these to replace the machine heads on my Epiphone Sheraton II, and they are easily the most solid tuners that you can get. The locking mechanism is easy to use, and grips perfectly, making string changing really quick. These are essentially the same as the ones on my 2008 LP Standard, so I ordered more of the same for the Epiphone. I wouldn't buy any others.
