Guyker Guitar Machine Heads (3L + 3R Handed) – 1:21 Sealed Tuners Tuning Key Pegs with Big handle Replacement for Electric, Folk or Acoustic Guitars – Chrome, GK102C

I bought these to replace the absolute dumpster fire, garbage tuners that came on an old Ovation Celebrity I picked up. They fit perfectly, turn smoothly, were simple to install and feel more quality than what the price would suggest. They seem to hold tune pretty well and am overall impressed. The pegs are a bit larger than the ones that came on the Ovation originally, which isn’t a big deal. Thank you.

Guyker is knocking it outta the park. I've used several sets of their tuning machines as well as other parts and I have not been disappointed by any of them. The tuning machines have been as good as if not better than much higher priced brands I have used in the past. There hasn't been any issues with them holding tune whatsoever. Whether you get locking or non-locking you won't be disappointed by them. They are a great value and are easy to install. They fit most all import guitars as well as domestic. They offer a variety of different colors as well so you can get the boutique look of a custom made guitar.

Great tuners, super smooth, and nice high ratio… meaning it takes more knob turns to turn the shaft. 1:21 = for the shaft to turn around once, it takes 21 rotations of the knob, this allows for very easy micro adjustments in tuning. So you can hit your note with ease rather than bouncing around your notes back and forth. (I saw a previous commenter said his shaft didn’t spin, but if you look closely at his video, it is, he just didn’t understand high ratio tuners) I build, fix, and upgrade guitars as a side hustle/hobby I will be buying a lot more of these and using them. I can fully recommend these. I put my first set on a vintage 70s Univox lawsuit era Les Paul copy, and they were so good I’m here to sing their praises. If you don’t know these are copies of Grover tuners that were a very popular upgrade for Les Paul players.

I bought these as replacement tuners for an older guitar. After installing them, I found that one of the right-side tuners didn’t work properly. I contacted their customer service directly, provided pictures, the model number, and specified which side the tuner was on. They quickly sent a replacement without any hassle. Their representative kept me updated every step of the way, and the new tuner worked perfectly. Overall, I’m very satisfied with both the product and the service. 10/10 for customer service, and 10/10 for product functionality and fit.

I’ve used these on a couple of guitars and they work great. They look good also and were easy to install.

I needed to replace the tuners on my Yamaha FS800 guitar. I bought these gold colored Guyker Tuners because another review and the summary review stated that these would fit. They certainly fit and as suggested by others, the gold colored ones really fit with this guitars color. They fit with the existing 90 deg screw holes and in the tuner holes on the headstock. My grandchildren will use this smaller body guitar and be proud of how it looks and functions.

I purchased these in July and just put them on an acoustic guitar. Installation was qu8ck and easy. But...... After I installed them, and tried to put strings on, I found that the tuners did not spin at all. You can spin the handle but the post remain still. Bummer. I had wanted to like these things.

I’ve used Grover tuners for years. I like them but they wear out and get wonkey. I needed to replace a set of Grovers on a cheap guitar and opted for these. They are great and for $22 USD are a ridiculous deal!

Insatisfait ! J'aimerais en avoir une de remplacement car l'une des clé ne fonctionne pas donc commandé et payé pour rien ! Vraiment décevant ! L'une des clé n'a pas de filet donc je ne peux pas utiliser et donc elles ne servent à rien car j'ai besoin de l'ensemble !

Good quality machine heads however the length of the tuning posts are a bit on the short side (Tanglewood acoustic) but still usable. Good tuning stability and smooth mechanism. Budget machine heads that resemble Grover.

Very good quality, and a great alternative to far more expensive machine heads

Good upgrade for budget guitar

Well made fitted perfectly.
