I dropped my guitar and broke one on the Rotomatics. When I called Grover to see how to get just one machine head, they told me that all Grover's were guaranteed for life. I told them it was my fault but they said no problem and sent me a no charge replacement out the same day. They wouldn't even take any money for postage. I wish more companies were thsi good. EXCELLENT!!!

      Comments about Grover-Trophy 102 Rotomatics 3-Per-Side Guitar Tuning Keys:

      Normally I cannot knock grovers out of tune for nothing, even on childrens guitars, but I have had a problem with an Epiphone Les Paul which is not even a year old. Other people have also had problems with their Epiphones. The new tuning keys did resolve this problem however Grover informed me that the 102c's Musicians Friend sent me are probably 14:1 gear ratio. They no longer manufacture 12:1. There was nothing on the package to indicate the gear ratio. Grover also told me the keys on the Epiphone are probably also 14:1. The keys were almost identical with a slightly different casting mark on the bottom. I did not have to resize the key holes and the screw holes were the same. I have played guitar for 50 years. It is always preferable to go to a lower gear ratio if possible. 12:1 or even 10:1 if you can find them. That means that one gear will turn one full turn while the other gear will turn 12 times depending upon the gear statistic. If you think about the gears on a bicyle,if the gears set one way it is easy to pedal. If the gears set the other way it is harder to pedal. The closer you get to that 1:1 gear ratio(gears of the same size) the harder it is to turn. If you have a tuning problem with your guitar go to a lower gear ratio.

      Comments about Grover-Trophy 102 Rotomatics 3-Per-Side Guitar Tuning Keys:

      These tuners did improve my guitar in terms of tunning. The olnly thing I noticed was that the description says they are a 12 to 1 ratio. They are in fact 14 to 1. Not a deal breaker but thought it should be mentioned...

          I ordered a set of these to replace the low quality,rough feeling, unstable tuners that came on my Epi Les Paul 100. They dropped right in, look fantastic and work great. I highly recommend this product.

            Comments about Grover-Trophy 102 Rotomatics 3-Per-Side Guitar Tuning Keys:

            I bought an Epiphone Les Paul 100 as a practice Guitar and immediately disliked the tuners. Bought this set of Grovers and installed them in about 30 minutes. I was hoping they would just pop in the same hole whithout a need to ream out and they did. The existing tuner hole was .37" and the Grovers were .39" - the difference didn't matter on this guitar. These are great tuners and will last the life of any guitar you have and will hold tune with no problem -- not to mention a lifetime warranty. How cool is that? --Rock On!

                  I e-mailed MF customer service and asked for direct replacement tuner recommendations for a BC Rich Mockingbird Contour Deluxe electric guitar. I specified I wanted tuners that didn't have to have new mounting holes drilled into the headstock... you know.... direct replacement tuners. Customer service sent me two suggestions, of which these were one. I ordered them... confident they would meet my criteria. Upon arrival, these tuners were NOT direct replacement tuners. Lesson learned. Next time I'll do the research myself. This customer would have been better served with a "we don't know" response from customer service... because they didn't know even though they said they did. The 102 Rototmatics however, are quality tuners that I've used before. They just didn't fit.

                      Changed out the Robot keys on my 2015 Les Paul with these...They fit perfectly,just line them up and drill small pilot holes and screw in the screws that are provided...Nothing to it,took me about 20 minutes.

                        Ok, I didn't have to pay for mine, I got them off a guitar that my cats managed to break. Stuck them in a jar incase I needed them. Then I bought an Epiphone Les Paul Special 2 for a very good price. After playing it for a while, I was not too happy about it not staying in tune well, so I decided to try swapping out the existing tuning heads for the Grovers. I thought it would just be a straight swap, but I needed to drill out the existing holes to get them to fit. It's easy enough to do, but you need to be careful not to split the wood. Once I got them in place and put some new strings on, it was like a completely different guitar. Definitely recommended as an upgrade for any guitar that has problems staying in tune.

                          I wish I would have gotten these first instead of switching bridges and the nut on my Gibson. These are heavy duty and the gears don't move around after you tune it which is the cure for a problem guitar. If you've got a problem guitar in your collection, get these. You won't be disappointed.

                              Used these for a custom guitar build. Good quality tuners, no lemons in my set, they all turn smoothly and keep the strings in tune. They look very nice. Easy on the budget. I did have to drill larger holes in the head stock for these to fit.

                                I installed these on my Epiphone Les Paul 100 because it would not stay in tune. The only drilling I had to do was for the set screws on the back of the kneck. The guitar stays in tune and the tuners do not slip when I play solo's or bend the strings.

                                  Replaced the Tuners on a Martin DSR Custom with the Grover 102 Rotomatics. Perfect fit with no drilling. The Martin already sounded Awesome and now it tunes up Awesome and holds tune Awesome.

                                      I've used them as replacements on several Gibsons and they stay in tune. Notice the giant period mark?. Smooth. Installs very quickly. I hated to have to replace my 1959 LPJ tuners, but I had no choice. It was mine and a players guitar. The price has gone down over the years. How many products can you say that about? Maybe I'm foolish for even bothering to write a review. Well, whatever. They are your
                                      Gibson replacements. Schaller is your Fender replacements. It's the way of the universe.

                                        I had to open the tuner holes with a hand T-Reamer. Takes some time but well worth it. Works as stated by mfg and improved the sound of my SG. Next time will try the locking tuners.

                                            i called Grover to report a slipping tuner and they said something wrong with my guitar i swapped tuner locations and the problem moved to the new location i have been playing guitar for over 50 years and i know a bad tuner when i have one in all fairness they did tell me to send in the old tuner and they would check it out and send me a new one at no charge, i will be changing to waverlys thanks Grover I didn't want to be without my guitar for that long of a time.

                                              Great tuners. put them on my Epiphone Les Paul Special. Feels like a whole new guitar, really stays in tune. Stayed in tune for the whole gig. Did have to modify tuner peg holes. Nothing major.
