Guyker Guitar Locking Tuners (3L + 3R Handed) - 1:18 Ratio Lock String Tuning Key Pegs Machine Heads with Hexagonal Handle Replacement for LP SG Style Electric, Folk or Acoustic Guitars- Chrome

I got these to upgrade an 95' Korean squire stratocaster. I had to ream the holes on one side if the headstock slightly about halfway through for the bushings on mine. The screw holes didn't line up in my case. So I plugged the old and drilled new ones. It was easy with basic tools and available youtube do it yourself videos. I'm very impressed with the function, and overall build quality. Will never have a guitar with out these in the future.

Works as should. Good quality for price

The fit and finish on these tuners is excellent. They lock well and have held tune. The only issue I have is one or two of the tuning keys have rough areas of travel where they aren’t as easy to turn. I’m hoping some WD40 in the joints will fix this. Other than that they are as good as much more expensive tuning machines.

I have used at least 15 of these without any problems. My only suggestion is to screw in all the top Ferrels as soon as you get them. Twice I have gotten a batch with stripped threads. Aside from that, I would rate these as good as the Fenders.

The price was right, but these are not smooth tuning machines. These actually look nicer than I was expecting. There is a nice finish to the back plate of each tuning key. I had great expectations for how they would work. Once they were on the guitar and under a load they feel cheap (which they are) and don't turn smoothly. They will stay in tune, I'm sure, but the process of tuning them isn't as fun as on a well machined tuning key.

I installed these on a semi-hollow (Florentine) guitar similar to a Les Paul. They were well finished and installed easily. Though the threaded, string lock part can be screwed all the way out (and lost) and almost must be to have space for a bigger string, they do work well. Tuning stability has been very good and string changes are easy. The price is more than fair for tuners of this quality.

These tuners fit perfectly in my Epiphone Les Paul 100. I was wanting to blacken it out so I replaced the chrome tuners with these. The locking device works good like they are supposed to. The Ernie Ball Slinky strings work great with the tuners as well. I hope this helps because I’ve read other reviews that say these don’t fit Epiphone Les Pauls but they do, at least the 100 series.

These tuners are pretty much junk. They get super stiff and harder to turn as you increase the string tension and get up to tune. They have burrs in the manufacturing and break strings all the time right at the tuning peg. It's not just me, my guitar tech who works on hundreds of guitars a year has seen the same thing. Spend a few more dollars and get some Gotoh or Fender or other good tuners the first time and save yourself the frustration of finding out how shoddy these are.

Una de las guías para atornillar venía mal y no se podía atornillar. Algunos materiales son de calidad pero otros son muy malos.

Cool

Also habe diese Tuner zum ersten Mal getestet und bestellt. Wurden an einem Fender Stratocaster Hals verbaut. Äußerlich sehen die Teile gut aus, aber das innere System ist verbesserungsbedürftig. Ein Tuner ist sehr schwergängig und müsste dringend ausgetauscht werden. Zuviel „Freilauf“ im Drehen gibt es auch. Der Mechanismus greift oft erst etwas später. Ich muss sagen, dass die Qualität dieser Tuner nicht wirklich berauschend ist. Dann lieber Kluson, Original Fender o.ä. - werde die Teile wohl wieder zurückschicken. Wenn der Service mir den einen Tuner ersetzt und zusendet, kann ich meine Rezension noch einmal überdenken. So ist aber leider ein starkes Defizit in der Qualität zu verzeichnen.

Starting with the 3rd string and going up to first string, these "locking" tuners wouldn't even grab the string when srewed all the way in. The string would just slide right back out. I guess you get what you pay for. They were completely unusable and now are in the recycling bin. I bought some Gotto tuners and they work like a charm.

All good very well made
