guyker6 Inline Vintage Guitar Lock String Tuners – Locking Tuning Key Pegs Machine Heads Replacement for ST TL Style Electric, Folk or Acoustic Guitars – Chrome

The locking refers to the string in the hole not the ability to lock the twisting tuner peg from twisting.

Every set I’ve bought work amazing

For the price they are great. I can only give 4 stars since they are not all supper smooth. Still an inexpensive and worth while upgrade for a cheap guitar.

I recently got a silvertone 1478 reissue on sale. It was very affordable so I expected a few parts would need upgrades.I've used this brand for my other modern guitar tuners but I've never had vintage style tuners. The guitar was having some tuning issues so I tried a few things. Ultimately upgrading to guyker tuners resolved this.The installation was easy. I did have to add 1 layer of thin copper tape to the ferrules because they were slightly too small for the holes. The movement of the pegs are smoother and sturdier than the factory pegs. There's very little play or jumping so they function much better while still looking like the factory retro tuners.

I've been building guitars for 15 years, and have used every tuning machine brand and model under the sun. These tuners, specifically the Pro version, are among the best I've ever used. The gears feel like a $400 set of Waverly machines. They are astonishingly smooth and have less backlash than 90% of name brand machines. For the price, they are BY FAR the best value for the money. I will be using these before Grover, Wilkinson, Gotoh, Kluson etc. They perform as well as Hipshot tuners for almost 1/4 of the price.My son and I built a guitar for him, and I bought these because I was wanting to save some money. I just figured these would get me by until I could save up for some nice Kluson machines, but these tuners feel even better than the Kluson's and will be a permanent fixture in my shop from now on. I've already recommended and installed them for several clients since then, and they all love them.The finish is very nice, as well. No obvious plating defects or burrs. Very clean and smooth finish.The locking mechanism is well machined. The tolerances aren't absolutely perfect, but they're good enough to work as if they are perfect. Other budget brands have WAY too much slop and do not effectively lock the strings. I'm 100% confident in these locking mechanisms ability to hold the string in place. We've had no issues with slipping, and we've played the guitar hard and well for about a month now.Finally, the dimensions are perfect. No odd sizes, holes in the wrong spot, stamping/machining inconsistencies, etc. The dimensions and layout are exactly what you'd expect and match their spec sheet.I really cannot recommend these enough. I applaud the team who were behind these. They did an excellent job and clearly cared about the end result, which really shows. It's not often a budget brand releases something of this level of quality, so I have a ton of respect when they do. It's an incredible value for the price, and I could not be happier with my purchase. Time will tell how durable these are, and I will update my review if any issues do arise, but I expect that I won't need to do that.

Direct swap for my squire classic vibe 50s telly, locking mechanisms hold tight and holds tune so far.

Look cool but the little screws that goes in between the tuners are horrible. Even with a drilled hole they still strip or break. That kills the quality.

Installed on a classic vibe Squier Mustang. Dropped right in with no reaming required. I can't state how good these tuners are for the price. I have Fender locking tuners in another gutair and these are just as good. If you are considering these to upgrade a Squier, do it. You won't regret your purchase. 🤘
