6Pcs Guitar Locking Tuners (3L + 3R Handed) - 1:21 Ratio Lock String Tuning Key Pegs Machine Heads with Hexagonal Handle Replacement for LP SG Style Electric, Folk or Acoustic Guitars - Chrome

I found these tuners easy to fit, the one screw lined up with the existing hole and I like the locking feature. A well made tuner.

Excellent tuners. This is now my second purchase from Guykers and both tuners work really well. Great value for money and ease of use is through the roof, don't have to sit there winding due to locking tuners. The 1:21 ratio is a game changer for me especially considering I'm using this on an acoustic. Contrary to what others will say, it DOES improve tuning stability, which makes sense cause you have to go strike the strings harder for longer to get out of tune than with a 1:18 ratio. The feel is one of stability. It also looks great in chrome. Might get another black pair for my electric guitar. Really good!

Good tunner, hold well Honestly product

I cannot begin to describe how happy I am with these tuner’s they look amazing and work incredibly well I really thought that me fitting these machine heads would be a step too far for me and I may have to seek help from a professional luthier but I decided to bite the bullet and have a go myself and I’m so glad I did I did have to drill the headstock (I think that aged me about ten years) having to drill 1 hole on my headstock would have been bad enough but having to drill 12 holes made me so nervous but taking my time and patience and being very careful the holes were drilled and they fitted perfectly now restrung and tuned up this guitar sounds amazing I cannot recommend these tuners highly enough if you’re thinking of changing your tuner’s give these a go you won’t be disappointed

A few months ago, I bought a value for money guitar and everything was great apart from the tuners. When tuning the guitar, the standard tuners would 'jump' making it difficult to be precise with the tuning. I was apprehensive about swapping the machine heads and worried about whether the screw positions would be in the same spot as the originals. Also would more expensive ones be a better buy. I need not have worried. The Guyker machine heads are well made, quite solid feeling and fit perfectly on my guitar. The locking mechanism makes changing strings a lot quicker and hold the strings in tune as you would hope the would. I went from some 11 gauge string down to 9 gauge and it took a little while for the guitar to settle into the lighter gauge. The following morning was delightful, picked the guitar up and all stings were still 'spot on' in tune. I'd have no hesitation in recommending these tuners, great value for money and an ideal upgrade to the stock tuners.

Bought for grandson who was pleased as he had been considering buying them himself

These machine heads/ tuner's are a fantastic upgrade for my Epiphone Les Paul special Vintage Edition. I was on the fence for a while after reading some negative reviews. I took a punt anyway and am so glad I did! They stay in tune, they are perfect and much better than the crappy stock ones that came with the guitar! Thanks Guyker. I recommend and will shop again.

I have bought these in the past and been very happy with them, however this time had to strip two of them down ,as they were sized up and slightly cross threaded now fine
