### ⭐⭐⭐⭐⭐ Great upgrade.
*by W***N on March 23, 2021*

I installed the Guyker Guitar Locking Tuners (3L + 3R) - 1:21 on my Ibanez AWD82T along with a Graphtech Tusq XL PQL-6010-AG nut. I used a $30 digital caliper I got on Amazon to get the nut to fit with some sanding but then it fit like a charm. I strongly recommend having calipers if you’re a working on a guitar; you can use them to determine if these tuners will fit your guitar, and they are handy around the house for other chores. I selected these because they looked like the original tuners half-melted. These tuners were a drop-in fit with the posts matching the headstock holes and the anchor screw holes aligning perfectly. If the replacement anchors screws are smaller than the original anchor screws I recommend using the original screws. Otherwise the smaller replacement screws may strip-out the hole and not tighten properly. Not that they needed it, but it’s my standard practice to lube things I’m assembling so I sprayed the gears with Dupont non-stick dry Teflon and they turn smooth as silk and the 1:21 ratio makes for precise tuning. I’ve not had any problems with the guitar holding tune. Alert, you have to pull the string up to the top of the peg hole so the locking shaft clamps it at the top, not on the side. Otherwise the string will be on the side of the locking shaft and slip out of as you tighten the string. Again, pull the string tight through the peg hole and lift up to the top of the post hole so that when you turn the locking screw the shaft meets the string at the top and locks it. I find the materials and engineering of the tuners to be above their price-point and I’m totally satisfied with them.
