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.

      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.

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

      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.

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

          I picked these up to replace the stock set that came on my 1999 Art and Lutherie acoustic guitar. My acoustic sounds great but the tuning keys couldn't keep it in tune after a few songs. I picked this set as they looked to be the best value. They were shipped fast and got here almost faster than I installed them on my guitar. It was very easy. It took less than an hour to take the strings and old keys off, drill out and screw these news ones in and strings back on. Couldn't have been easier. I've been playing on them hard for a week now and couldn't be happier. I shouldn't have waited so long.

                  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.
