Having already purchased a pair of their 3R 3L locking tuners before these I sorta knew what to expect coming into installing and using these tuners and I wasn’t wrong. These tuners are just as great as every other Musiclily product I’ve ever used.These tuners were a fantastic upgrade for my Squier Bullet HH Mustang. Fit and function on these tuners is fantastic. The stock tuners were very loose in the holes, these fit so much better, they’re much closer to the actual size of the tuner hole. I also want to mention that the washers on these are significantly larger than my stock tuners which helps a ton holding them in place. These have alap improved the break over angle at the nut on my Mustang a lot.Installation was easy as pie, all you need is a 10mm wrench and a small Phillips screwdriver. Beyond that, pull the strings thru, crank the hold down screw down, cut your string, tune it up and you’re ready to go.I’ve really got nothing but positive things to say about these tuners. I would happily buy another set of these again. These along with all the other Musiclily products I’ve tried have been an amazing value.
