Guyker Guitar Locking Tuners (6 for Right) - 1:18 Lock String Tuning Key Pegs Machine Head with Hexagonal Handle Replacement for ST TL SG LP Style Electric, Folk or Acoustic Guitars - Black

Smooth tuning. Stay in tune. This is a locking tuner so if you screw the thumb wheel out to the limit (but not beyond because you might damage the screw or break it off) you can lube both the worm gear and the main gear inside.I dip a tooth pick in the grease and put it on the gears inside the tuner. Looking inside it looks like brass gears. I lubed it with lubriplate, a Lithium based grease. I suspect all geared tuners use brass gears so lubing with Lithium grease is a very good idea. It also helps to give the tuner that silky smooth feel.I adjusted the tension with the philips head screws in the tuning knobs. Ultra-smooth tuning.I had to drill holes for the screws because the old tuners used a peg (Sperzel tuners) instead of a screw. No problem. I was very careful about drilling the correct size hole and using screw lube on the threads so I would not break or strip the heads any of the phillips head screws.Note on adjusting the screws that hold the knobs in place: Do not loosen these too much or the tuner will bind because it will allow the worm gear to pull outward slightly while the knob is rotated. You can see this happening if you look closely at the back of the tuner. For smooth operation the screw has to be pretty snug but not tight. You can judge this by rotating the knob and feeling the torque required. Using a string winder gives you the feel for it.The appearance of these gold tuners is right up there with my Grover and Schaller tuners on other guitars. Those tuners were over a hundred bucks.I love the Guyker 18:1 tuning ratio. It makes tuning more accurate and faster with the smaller knobs on 6 inline tuners. The Sperzals had only a 12:1 tuning ration which is to coarse for me, particularly with the smaller tuning knobs on a strat-style guitar (6 inline).I have found over the years that Guyker parts have just as good quality and life expectancy as the higher priced tuners. It's pretty surprising. Don't let the low price convince you that it's low quality. I don't know how they do it, but the quality is great. I found that to be true of all Guyker parts that I have purchased including Bridges, String Stops, and now tuners. So these days my first choice is Guyker and if they don't have what I need I look to the higher priced stuff. All the big name brands have much higher prices, but my experience is that the quality isn't any better than Guyker. Maybe i shouldn't say this because Guyker might raise their prices!I don't get paid for writing this review and am not afilliated with Guyker. I just appreciate high quality and affordable prices. I own about 22 guitars (kind of lost count) LoL. And I work on them all. I love working on guitars (and playing).

The media could not be loaded. Needed to upgrade the tuners that came with my Chinese "tribute" Les Paul. The stock ones were garbage. These Guyker locking tuners receive a lot of positive reviews so I figured I'd give them a try. For only $35, why not? I bot these because I like the look of vintage Gibson tuners, but wanted chrome to keep the aesthetic of the guitar. They installed perfectly. No issue with lining up the screw holes on the rear of the headstock. These are my first "locking" tuners and I have to say, I'm going to be upgrading all of my guitars now! The rotating dial on the back holds the string in the post hole to allow easy winding. They're solid. Real metal. The turn is forceful, which is good because you don't want loose tuning keys. My only complaint is the posts are a tad shorter than the stock ones. Otherwise, I think they're great! Highly recommend!

After buying my first new guitar in years (an Ibanez S Series), the stock tuners were just not holding up and I was adjusting between every song. I was eyeing up some Hipshots (which would've been more than double the price of these), when the Guykers popped up on my feed. The high reviews/affordability sold me and I took my chance.Putting these on, it was life changing. They look amazing with a Satin Black finish, and installing took maybe 10 minutes tops. The string tension is ROCK SOLID, and makes for a snappier action which I personally love on all my guitars. Tuning stability is now something I barely think about. I tune it once when it comes out of my case, and I might have to adjust once during an hour long rehearsal IF I HAVE TO AT ALL.***It should be noted I tune into Drop A, with .13-.62 Baritone strings (with a wound third), so when I tell you these are up to the task, they handle damn near anything***I was so impressed with the Guykers that when my second lil guy (LTD TE-200DX tele) showed up, I knew no matter how good the stock tuners were, they'd have Guykers on it within the week, and I made good on that promise. It's turned a near-perfect mid range instrument into my favorite axe to reach for, from studio to gigging to rehearsing for hours. The days of spending $100 on one set of tuners are done, I'd pit these against any set of Hipshots, Schallers, or anything high-end.
