These are an exact fit for my Epiphone Les Paul. Easy install, and work great. I had no issues with the locker stripping the the threads as one reviewer had. One of them does feel a little gritty, but it tunes as it should.

I swapped out the tuners on my Epiphone Les Paul Traditional Pro III Plus for these Guyker tuners. They were a perfect fit, with no drilling necessary.So far, the quality seems just as good as the Grovers that they replaced. Smooth turning and they stay in tune, the locking mechanisms are solid and easy to use, and they look nearly identical to the original tuners.For the price, you can't beat these.

These tuners are an incredible value. Perfect drop in fit for my Gretsch 2627tg, same as the much higher price Grover 502's. The finish was good, matched the existing gold hardware well. The locking mechanism held the string tight and has had no slippage. The tuning stability has been great, much better than the stock tuners, especially with the use of a Bigsby vibrato. Only one star knocked off because two of the tuners had some "grit" to the gears when first using them. Time will tell if that will reduce with regular use, but out of the box they were not as smooth as some of the higher end tuners, but that's to be expected at a roughly $30 price point. Overall, extremely happy with this purchase and would recommend.

Very easy to install, and the locking feature makes tuning and installing strings very easy. Very nice gold finish. Tuning was very smooth also.

Bought these to replace the stock TonePros tuners that came on my Schecter C-1 Platinum Blackout guitar. Nothing wrong with the stock tuners but I wanted to have locking tuners for ease of string changes and tuning stability. They were a perfect match to the stock holes with no modifications required. Seem to be well made but only time will tell. The only difference was that the tuner pegs/shafts are just a bit shorter (3mm) so they are a little lower profile but no issues from this. Also they are 21:1 gear ratio so very fine tuning adjustments.

What good are locking tuners when they don't actually lock? They installed easy and look great, but after stringing up my guitar the very first time 3 of the tuners will not lock the string in place. I am unable to actually screw the tuners in place to lock the strings. The tightening mechanism will not "grab" and further twist in to lock the string. It is almost like it is stripped out. I cannot imagine it is stripped after only trying to twist them in for the first time. They locked fine without a string but when i unscrewed the locking system to be able to put in the string the locking system just turns and will not grab anything to tighten up. Strings are 10's so it is not that the string is to heavy of a gauge. Bought a different set for a strat guitar I built and those work 100% correctly and have had no problem with those . (another brand). My business will most likely go to that company for further multiple builds.

I also have a Gretsch 2627t with a Bigsby. After dryer to change strings the first time the traditional way ki found out I didn't have enough striing to wrap around the post on the lower E string. That's when I decided I needed looking tuners. These tuners were easy to install myself with no problem. Will buy again

I installed these on a guitar with 10s. The tuners would not stay tight without regular tightening with a screwdriver.Movement was lumpy on the bottom three strings. String locks appear to work correctly but I could not keep the guitar in tune. Having suspected the tuners, I replaced them and the guitar now holds its tune.These tuners were not good enough.
