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

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!

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.

Guyker is great. you cant go wrong with them. good price and very good quality.

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).

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.

They appear to be well-made and reliably do what they're supposed to do. I've had no tuning issues since installing these several months ago.

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.

Don't laugh, These tuners work perfect and upgraded the look to the guitar. Note, I purchased two bridge pickup covers for both the neck and bridge, and new knobs tone/volume. I did some additional upgrades to an '88 Kramer. The pickups were upgrade back in late 90's to Seymour Duncans. The new upgrades included the chrome pickup trims, and covers and locking tuners. The guitar looks and sounds great on stage. Completely stays in tune with the Floyd Rose (original). I did do a complete setup on the guitar. Perhaps is was time for some LUV

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.

Avevo preso degli autobloccanti della Musiclily ma perdevo in continuo l'accordatura perchè le viti di serraggio non trattenevano bene le corde, specialmente se usavo il tremolo. Ho reso e poi deciso di provare questi Guyker, che costano solo qualche euro in più degli altri. Diaciamo che sono un po' più carini e meno grossi. Già a prima vista si nota la differenza in qualità ed in ogni caso sono ben assemblati e non presentano gioco o difetti. Montati senza nessun problema, vanno bene e fanno il loro dovere egregiamente. Per ora devo dire che sono molto precisi e permettono micro regolazioni tali da avere un buon tuning. Sono molto soddisfatto visto il prezzo.
