Review: Good Ovation Celebrity Tuner Replacements. - 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.
Review: Guyker is getting it done! - 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.

## Features

- Package includes: 6 pieces (3 for Right, 3 for Left Hand) guitar tuners pegs, 6 mounting screws, 6 threaded bushings, and 6 ferrules, good replacement for many electric, folk or acoustic guitars.

### ⭐⭐⭐⭐⭐ Excellent high quality tuners
*by S***S on January 22, 2026*

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.
