Ditch your old machine heads and upgrade with these Pro Tune Locking Tuners for your Guitar.

These state-of-the-art guitar locking tuners are designed for acoustic and electric guitars and only use one discrete location pin instead of screws.

They feature a user-friendly locking system located on the back of the machine head utilizing a knob for simple twist-to-lock or release.

This drop-in, no screw design comes with all mounting hardware and is an upgrade to your factory machine heads in appearance and gear ratio.

Improve your tuning when you use these Pro Tune™ Locking Tuners.

The Science:

The concept behind the locking tuner is very simple. A little clamp inside the tuning post actually grabs your string and keeps it from coming loose and you can tighten it with a little knob on the back.

The idea here that a lot of people are missing is, this prevents you from having to wrap the string around the post. The reason why that creates a problem is when you bend a note or use the tremolo system, it actually becomes slightly unwrapped around the post.

So when you either unbend the string or return the tremolo back to the zero position, the wrap has actually moved slightly. This is what causes tuning instability and changes the tuning of the string, you don’t want that.

    My daughter's guitar had a tuner stop working. So I replaced them with these. For 10 bucks it completely woke up tone of the guitar. The only thing is; turning the tuners will tire out your hands they are very tight and not smooth.

    For the price, I’m extremely impressed! They hold the tuning well and don’t skip as of yet :) will purchase again if needed

    Pictures do not do these keys justice at all. If your looking to spruce up an old guitar or you just need to replace your current ones. These turn smooth. Look great. And will definitely add a bit of color to your guitar.

    Very nice tuners, great value for the money
    January 17, 2021
    Worked well to replace my older pegs that were pulling out screws as I turned the guitar. These attach differently and have the added front filler part that screws in to support it and keep it from being pulled down. No issues here. Love them!

    I bought these for my Fender Acoustic guitar. I was skeptical because of the price but I gave it a go. I had my local guitar shop put them on and change our my bridge and nut. The guitar is much improved. There is still some slop in one of the tuning keys but they are as good as the original keys that came on the guitar. If you are looking to replace your tuning keys with some that work these are the set for you. If you want a more accurate set and you are willing to pay 2-10 times the price of these, you will find better.

    This tuner set is better than my original Epiphone set. It costs only a fraction of the original product. I highly recommend this for all luthiers.
    January 7, 2021
    I installed them today. I'm impressed! They are much nicer than the stock Epiphone tuners I had. Tighter, smoother and make tuning much more precise than the awful stock ones. And you can't beat the price.
