Guyker 6Pcs Guitar Locking Tuners (3L + 3R) - 1:18 Lock String Tuning Key

Perfect fit and an excellent upgrade to a budget guitar helping to enhance it. The installation was super simple once I found the correct tools to use. Lack of foresight on my part. They feel sturdy, seem to hold tune better than the ones that came stock,and they look good to boot. If you need locking tuners, these will fit more than likely fit the bill.

Second set of Guyker locking tuners I've purchased and these (3L + 3R) are working just a great as the first set (6 inline for Tele). I put these on an Ibanez TCY621 acoustic and they swapped in perfectly without any issues. They fit so well on this guitar that I was able to reuse the original top bushing and and washers as well as the back screws. Locking function works as expected and keys turn easy and smoothly so far. Will definitely purchase this brand again for my mid to lower tier guitars when I need locking tuners!

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.

So much better than the stock tuners that came on a Chinese replica guitar. I think I've become a fan of Locking tuners. They turn with ease, no skipping or sticking. Was easy to install and the screws lined right up, didn't have to drill new screw holes. They feel and look good. I went and bought another set (in gold) for another guitar. So far the strings have stayed in tune.

Very nice item. Fit my Dean Vendetta XM perfectly. It's a great change from the original tuners, which were ancient and kind of bad. They're not the smoothest tuners I've ever used but more than sufficient for what I paid.

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).

Love these machine heads. I replaced some gold plated ones on a guitar I’ve been tweaking for no other reason than I’m just can’t leave well enough alone hehe. These were pretty much plug and play on a 2013 Fender Reissue Thinline Tele and they look awesome.

Man, these tuners are freakin' awesome! I have a Firefly LP James Hetfield copy, and I upgraded to these locking tuners. This'll be the fifth Firefly that I bought. The first four were great. They all had come with locking tuners, but I guess they're cheaping out, because this one didn't. It would not stay in tune! They must've put the cheapest tuners they could find on it. Anyway, these dropped right in, no problem! I also bought the Guyker roller saddle bridge, and I tell you what, this guitar literally rocks now! It stays in tune so good, and with that new bridge, it has sustain for days!! If you're needing some new tuners for your axe, I wouldn't hesitate to pick these up. Guyker has been making some killer stuff!!

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.

Gute Preis/Leistung, besser als so manch andere Tuner
