Grover 406C Mini Locking Rotomatic Tuners - 3+3 - Chrome

Love these Grover Rotomatics. Fit my PRS SE Custom 24 perfectly. Easiest locking tuners to make string changes once you know the secret of how to align the internal cam holes......turn the post till you feel the click.

As others have noted, these are a direct drop-in replacement tuner on (most?) PRS SE guitars.. everything including the screw hole lined up perfectly on the PRS SE Standard I installed them in, and looking at a PRS SE EG, they also line up perfectly for that guitar. I ended up using the screws, washer, and bushings from the PRS tuners; I may also swap the knobs out in the future, if the PRS ones will work (not sure.) [March 2012 - I finally got around to seeing if the PRS knobs would work on the Grover tuners; they will not.. so if you buy these for a PRS SE, be prepared for your guitar to look slightly off "stock". Bummer, as I do like the look and feel of the PRS knob much better.. but then again, with these tuners, hardly have to touch 'em.] One thing I've heard some people mention about locking tuners is that they weigh more.. I didn't think it'd really matter either way to me, but for the fun of it I figured I'd compare using my kitchen scale. I took the card with all six tuners in it out of the plastic package, and weighed the Grover tuners before swapping.. these 406c's come in at 7.05oz. After swapping the tuners, I put the six PRS tuners back into the same card, and weighed them.. they came in at 7.45oz. So the replacement locking tuners actually weigh less than stock. That may be due to the knobs (the Grover knobs are noticeably smaller); not sure if that would make up a full .4oz though. In any case, installation was quick (it took about 20 minutes from the time I removed the old strings to when the new strings with the new tuners were tuned up and ready to go), and after 'stretching' the strings a few times and re-tuning, they seem to be staying in tune pretty well. Time will tell! Also worth noting that these tuners had no problems at all fitting heavier strings; I installed a set of D'Addario EXL117's, which are set up for Drop D tuning, and the heaviest string is a .056.. not the heaviest string in the world, but as heavy as I'm interested in playing.

These are great pegs, work great, just wind them one or two turns after locked ....now, on to Traveler guitas and these tuners (I have an Eg-1 custom, ver. 2)---just thought I would add, because seems people with traveler guitars are looking for these tuners: As noted, the tuning pegs on traveler guitars are just terrible, and the pickup works…and that is all I can say (it is an Epiphone pickup, the $15 variety). I purchased Travels locking tuners, and they were just as bad at the original. I am going on a long trip, so I decided to try to get this sucker to sound good. I replaced the pickup with a Seymour Duncan JB Pickup, and took those terrible traveler locking tuners off and bought Grover 406c mini tuners. I had to make them a little off-set and drill a new hole for the small screw (not a big deal at all), but they drop right in. Now I love this guitar, sounds great....let me talk more about the Traveler guitar. So, what did this take: $550 for the "Custom, top of the line" guitar, $50 bucks to try the traveler locking tuners (shame on them), $80 bucks for the Seymour Duncan pickup, $50 more bucks for the Grover tuners. And let’s see, the setup, which I did myself, but needed much work….neck adjustment, lower action, intonation, etc. So at least $730 bucks for this sucker. If I had a shop set it up, that would have been another 70 bucks at least….so, if you travel a lot, and really want a guitar that travels well and sounds good, that is what it takes if you buy a traveler, custom, top of the line guitar, in my experience.

Perfect replacements for my Orangewood "Oliver" OM size acoustic. Instalation was a breeze... they were a perfect fit, and yes they work beautifully! They're moderately priced and I couldn't imagine a better choice. The 18.1 gear ratio makes tuning quick and smooth. These locking tuners are a wise option that takes the time and frustration out of changing your strings too. These Grovers are groovy!

One of the few things I didn't love about my 2017 PRS SE Custom 24 was the lack of locking tuners. I have them on other guitars and like the fact that they help tuning stability, and especially, make string changes very, very easy. I was told these tuners were good a drop-in option for PRS SE Custom 24, so I ordered these in matching chrome color. Installation was very easy, as you'd expect with a drop-in fit. It was just a matter of a nut and a screw to remove the old stock tuners, and reverse that to install these tuners. It took me only a few minutes while changing each string in the process. Once in place, I was not used to these kind of locking mechanisms. Unlike the Ping/Fender locking tuners (and others), there's no wheel to engage the locking mechanism with these - you simply tune the string up to pitch and the locking mechanism engages. It seems like a leap of faith at first, but it works well once you get used to it. The operation of the tuners is very smooth overall. I'm very happy with that and the high gear ratio, which makes it easy to obsessively tune with precision, as I often do between songs. They definitely add an element of tuning stability over the stock tuners, particularly when using the whammy bar, though having a well-cut, lubed nut will also affect this tremendously.

Great tuners, easy install, work as expected,....BUT,......I was short one screw in sleeve on my order. How this happened I'm not sure, since the screws, sleeve and washer were in a sealed plastic wrap. I've improvised by using the sleeve from the tuner I replaced, but I'd really like to get the full amount of components that are supposed to be here. Guess I'll give amazon a call in the morning and see if we can get this sorted out. Tuners work great and were a direct drop in for my PRS SE24.

Great product. Wasn't quite sure how it worked. Watched a quick video on it. About as easy as it gets. Installed them on a Gretsch Electromatic without any modification needed.

I got mine yesterday and installed them on PRS SE Custom 24 30th Anniversary. The stabilizing screw holes were off by a smidgen (Grover ones are just a bit short), but wasn't too bad. I screwed in the screws most of the way first, tightened the bushings, then tightened the screws. All set. The Grover screws were just a tiny bit too thin. So I ended up using the screws from PRS, I was a little apprehensive because I've read other reviews stating the PRS buttons won't fit, but mine were a perfect fit. One note, tho, I have a set of Grover non-locking tuners I took off Epiphone Les Paul, and indeed, PRS knobs will not fit on those, but PRS knobs also fit on the Grover locking tuners I put on that same Epi LP. So maybe Grover changed the shaft dimensions? (pic posted) I've also read the reviews stating string breakage. The instructions included is different than on Grover's website which shows the string holes should be more or less parallel to the strings when you start to tune/tighten, the instructions in the package shows to have the string hole line up perpendicular to the strings. And so far I've not had an issue with D'Addario 095 - 044 set. (pic posted) I installed them late last night, and this morning, I find the strings have already mostly stabilized and I'm getting pretty decent performance from the locking action - not as good as Floyd Rose, mind you, but even with dive bombing the trem, it stays tune well enough to finish a song. So far, I'm happy.

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!!!

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.
