Grover 406C Rotomatic Mini 3 per Side Self Locking Machine Heads, Chrome

I bought a PRS SE Standard 24 just over a year but haven't used it because its tuning stability was hopeless; literally only lasting a few minutes. I love everything else about it but it was unusable. New strings made no difference so I finally decided to do something about it and, after some research into what seems to be a common problem with these guitars, I replaced the nut with a Graphtech PT-6643-00. That did improve things, but didn't cure the problem. I bought these tuners because there was firm evidence that they are a straight swap and I was recording with the guitar within an hour of installation - even on new strings. Some days later, I can pick up the guitar and play it straight off without tuning. The buttons are smaller than the PRS ones, they could be swapped if you don't like the look, but I don't care. Now I have a great sounding, and playing, guitar thanks to theses quality bits of hardware.

Allow some time for delivery.Well worth the wait. Straight swap for stock tuners in my PRS SE EG guitar. Feel the benefit straight away of locking tuners...no thumbscrew needed.Just locks as you turn the peg. I like the smaller tuner size but some people may not.All in all an excellent product.Turning ratio is great and tuning is rock solid.A good tremelo is made even better.

Wish I had ordered sooner, had to use the original screws from the old tuners. But the reviews and you tube vids recommend this. Guitar and tremolo stays in tune like a dream now.

as expected. Thanks.

Despite being advertised as suitable for acoustic guitars, the machine heads were nowhere near long enough. Misleading to say the least especially for the £75 price tag.
