    Excellent tuners

    I dropped these into my older, Peerless built Gretsch 5129. The string holes accommodated my thickest string, .052, without a problem. Others have said that nothing thicker than .046 will fit through. Grover must have recognized this problem and solved it. Also, others have had their high E strings break. Mine hasn't broken yet. It's a .10 gauge E. The tuners feel great and work as advertised. Tuning stability is much improved but it's not perfect. The usual culprits, the nut and the bridge, are not the problem. It must be the Bigsby itself - no surprise. Overall, adding these tuners was an excellent and inexpensive upgrade

    Just What It Needed

    Arrived on time. I was frustrated as the tuners on my main gigging guitar had started to slip even after adjustment. Ordered these on a Wednesday got them Thursday, had guitar ready for gig on Friday night. Had removed one of the old tuners and gotten all dimensions previous to ordering. These dropped right in and lined up perfectly. Had no experience with these automatic locking tuners. But they work and work great. No more having to re-tune every other song during a gig. Will consider using them as replacements on some of my other guitars when needed.

    Great Tuners!

    Another GREAT recommendation from my long time sales representative Chris McCown. Recently purchased a PRS SE 24 30th Anniversary model. Stock tuners were "OK". Chris recommended the Grovers as a do it yourself project. I am not a DIY kind of guy, and normally take these types of mods to my local luthier. But I was amazed and surprised, PERFECT drop in fit, easy to install, completed this myself with string change in under 1.5 hours! Makes changing strings a breeze. Best of all - they hold great tuning... This is my first set of locking tuners. Could not be happier!

    Certainly works as advertised

    Changed the tuners on a used PRS Custom 22. It was already 2 years old when I got it from a friend. The tuners on the PRS wasn't bad at all but I wanted something that would lock the strings in place without changing the nut to a locking type. While not the best Grover has to offer, these babies worked great on this guitar! Very happy. And install was very easy since these are made to match up with most guitars and fit perfect on the PRS. Plus, buying online from Sweetwater makes it easy and painless as it was with every purchase from them!

    Great tuners!

    These are great tuners. They do their job flawlessly. Also, these are a direct replacement for PRS SE models, no drilling new holes in the headstock. They hold tuning very well and do not slip. One thing I did find out through research is the holes on these will not accept anything larger than a .046 gauge string without modification. I was okay with this because I run .009-.042 strings.

    good tuners

    as always grover tuners work well i had to drill pilot holes bcuz i bought the wrong ones. All work fine except the low e and i think it might be because it's new strings.

    Great Replacement for PRS SE Custom24

    Great tuners. No drilling needed for PRS SE. Stay in tune well. These are a must have for this series of PRS guitars.

  • from February 8, 2016

    Great Fit and Function

    I bought these to replace the tuners on my PRS-SE245. Perfect fit; even the screw holes all lined up. I don't really like the mini knobs, so I just swapped the knobs off of the PRS factory tuners and put them on these and they fit perfect as well.

    Love 'em

    Bought these for my Jackson JS-30KE Kelly. They are a close fit due to Jackson's thick headstock, but considering you don't wind the string with these it's no problem. String changes are a breeze now even with the crazy angle at the nut and tuning is much more stable even with lots of deep bends (this guitar is a hard tail).

    Easy drop in replacement

    Purchased a set of these grovers to replace the tuners in my PRS SE Korina. I was very pleased with the ease of installation and locking mechanism.

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

    Great locking tuners ,they really do work. Just drop them in place of the PRS Paul Allender SE or any SE guitar.

  • from January 4, 2017

    Quality Stuff

    Easy to install, pay attention to location of screw hole when ordering. Work pretty well but not flawless. Didn't achieve my goal which was keping my PRS in tune for more than 10 minutes as others had success with these. I think the Problem is that PRS SE uses very light weight wood that is more susceptible to temperature changes beyond that its a mystery. My Ibanez stays in tune for literally months. These are nice although i would prefer a larger knob.

    Grover 406C tuners

    At first, I had difficulty getting the strings in the tuners.(My fault) Once I got it started ....it went well. I still find that 2nd,and 3rd strings "seem" to still slip a little. I think it is old strings that I will change out.
    Otherwise...I am well pleased and Sweetwater and my rep was excellent as usual and expected.

    Easy tuning

    Installed these tuners on my PRS se model and they are working great. Makes string change really easy all you need is a coin to loosen the thing but tighten a string is a breeze as the mechanism auto locks some how. My only complaint is that the bushing snap while installing and I'm certain I wasnt applying excessive force so be careful that worried me but they are working for now

    got this for my PRS so i can lock the strings especially in my lower tunings. The tuners don't even fit a string bigger than 46. don't waste your time or money find a better kind
