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.

These are excellent. Got em as replacements for the standard Marvel ones on my Gretsch 5622 - smooth gearing, the plating is very good and looks like it will stand up long term. Easy to use also - a real time saver when r re-stringing.

Passen perfekt auf die Guild 1512, deren Bohrungen in der Kopfplatte leider nicht 10 mm, sondern ein bisschen kleiner sind (US-Maß halt). Verglichen mit den wackeligen Originalen ist die Qualität der Grover-Tuner so überragend besser, dass die Locking-Funktion fast schon nebensächlich wirkt. Stimmen macht endlich Spaß, und wir haben ja eine 12-Saiten-Gitarre, weil wir gerne und viel stimmen :-D Die Locking-Funktion wirkt sich dann beim nächsten Saitenwechsel aus, und der ist bei 12-Saiten-Gitarren mit herkömmlichen (non-locking) Tunern bekanntlich besonders aufwändig. War erst skeptisch, was die Rotomatic-Funktion angeht (Verriegeln und Stimmen über den Wirbel, keine eine separate Schraube), aber wenn man es einmal durchblickt hat, ist es sogar einfacher. Klar sind sie nicht billig, vor allem weil man für die 12-Saiten-Gitarre zwei Sätze braucht, aber es ist eine riesige Aufwertung. Wer einmal Locking-Tuner hatte, will nie mehr eine Gitarre ohne.

È la seconda volta che le compro. Le prime per una chitarra elettrica Hofner Shorty, la seconda per una acustica Ibanez Talman. Avevo paura fossero piccole le manopole per l'acustica, invece stanno benissimo. Qualità top.

I highly recommend this product. The tuning became more stable in my LTD EC-256 and there’s no need to bore new screw holes… perfect fit!!!

Un clavijero de calidad, las puse a una guitarra tipo Les Paul que ya no conseguía mantener la afinación y estoy muy contento con el rendimiento de este clavijero. Muy fácil de cambiar las cuerdas y un funcionamiento muy preciso.
