Guyker 6Pcs Guitar Locking Tuners (3L + 3R Hand) - 1:21 Ratio Lock String Tuning Key Pegs Machine Heads with Hexagonal Handle Replacement for LP SG Style Electric, Folk or Acoustic Guitars - Chrome

As many buyers I presume, I start by looking at the bad reviews and it of course got me worried! Well, I'll tell you now, I have only good things to say! Installing is super easy, didn't have to drill, screw holes aligned perfectly. I measured and they geniunely have a 1:21 ratio, precisely. The main reason for changing the original locking tuners on my Ibanez - other than the ease of putting on new strings - was that I hoped to improve the tuning stability. The current Ibanez tuners would go drastically out of tune after a playing session or even over night...not anymore! 🙂 Despite it being winter now, meaning that the differences in temperature are really high between when the heat comes on and off at night, it stays very much in tune! (of course a very slight tuning is always necessary, as it would with any guitar tuners, but it's very much playable immediately). At this price point, there is definitely nothing better and I wonder if there is really any worthy improvement with some of the more expensive and established locking tuner brands out there?

Look great and nice tuning action.

Very good looking machine heads, they do seem to be very well constructed, they all turn very smooth and precise, I was worried as some reviewers mentioned that the high E and B strings could slip, so I did check the end of the pin and they all looked fine to me, installed them on a IYV IP-300-TSB guitar and they have been working fine for over a week, no tuning issues, they look really nice. I made sure to get the correct version, so they were a perfect drop in, so install was a breeze, I am so impressed that I am going to get a set for Strat (2 pins instead of screws for affixing to the headstock) and put on my MIM standard... if all goes good, I will also do it on my Tele... Re-stringing the guitar took a couple of minutes for all 6 strings, and with the strings being cut very close to the peg, the headstock looks very clean & tidy. No need to pay for the brand name, these look & work great, and the price is very good.

I upgraded some tuners to lockers and these have proved reliable and nice to use.
