Guyker Guitar Locking Tuners (3L + 3R) - 1:18 Lock String Tuning Key Pegs Machine Head Replacement for ST TL SG LP Style Electric, Folk or Acoustic Guitars - Antique Bronze

These have a good solid feel and appear to be well made. I had no issues setting these up or mechanical problems with them that I had seen in other reviews.With that being said, I was not a fan of the 2 little nubs on the bottom that assist in keeping them from rotating along with the screw. My guitar, a Gretsch Jet Vintage Select and Electromatic Hollow Body do not have the indents for that. I drilled a small indent in the finish to accommodate the nubs to keep the varnish from cracking while tightening.As far as tuning, an 18:1 ration would be better served but with a delicate touch while tuning they did just fine. These are holding quite nicely and keeping the Bigsby tremolo in check. I will be adding these to my Jackson and Les Paul that have tremolos as well.

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).

I bought these for my mod upgrade, the are not only beautiful but super effective at keeping my strings in tune, go get ya some, on my next guitar I will be buy another set, Luv these!

Great locking tuners at a great price. It is hard to beat these tuners at this price point. I put them on a PRS SE NF3 and they fit perfect. Highly recommend these. I also have vintage version on my Telecasters. All of them work great.

These work and look great with 1 tiny exception. I kept snapping high e strings when tuning. It turns out the locking mechanism is a bit sharp inside where the string goes through. You can remedy this by running a wound string back and forth through the string hole while ever so slightly engaging the locking turning “pegs” for lack of a better word. After that I had no more issues. And mind you this was only on the high e string.

Very impressed with the quality of the tuners. They feel solid, look very well made. Nice tight control of the tuning peg. However, can't really get a handle on how well they will perform until I get them installed on the guitar I am building. In the process of applying 25 coats of clear Nitro on the body. Don't anticipate installation until probably Sept. or Oct. Note: These things are heavy. I bought 3 sets to put on a 12 string / 6 string double neck guitar I am building. Remains to be seen if the guitar ends up neck heavy or not.

I was looking for for some good locking tuners for my Jackson SL5X FSR and I didn't want to pay as much as I did for a set of the Hipshot Grip-Lock 6 inline 21mm Locking Tuners I bought for my Charvel Pro-Mod So-Cal Style 1 HH HT. These tuners were cheaper in price, fit my Jackson SL5X FSR perfect, were easy to install, are far more responsive for fine tuning and made restringing my guitar far faster. I would say these help tuning stability at all like many claim, but since my Jackson SL5X FSR has a Floyd Rose on it I wasn't worried at all because the locking nut should take care of the rest. These are so good I decide to buy two more sets for two other guitars to speed up restringing because they're Floyd Rose guitars as well. IMO I feel these tuners would great for a hardtail guitar even better because of the 18:1 gear ratio making fine tuning a breeze. Excuse the sloppy stringing. I just redid my strings and it looks better now. These are reference picture just to show the tuners on the guitar.

Pretty good tuners they're pretty stable.

Excelente opción para un upgrade

Me gustaron aunque para modelos GRX IBANEZ queda algo pequeño hay que calar al tamaño y no cualquiera puede hacerlo por favor acercarse a un laudero de confianza para que haga este trabajo porque quedaría milimétrica mente mal y eso podría afectar la entonación y octavacion del producto final, aún así es un excelente producto muy profesional y de excelente material, si pueden agreguen un poco de grasa de litio en el engranaje para evitar corrupción por el óxido y muchas gracias por el tiempo de entrega súper rápido 🙇‍♂️ saludos.

Einfach genial!Super Optik!Und hält die Stimmung sogar nach Transport!Perfekt nur zu empfehlen

Bonne qualité, tête de mécaniques plus petites que ce qu'on voit habituellement (ce qui rend très bien sur une tête de manche PRS.

This is the third set of Guyker locking tuners I have put on guitars. For the price these are really good quality and feel smooth and keep things in tune.Highly recommend. My customers really like them
