Guyker 6 Inline Vintage Guitar Lock String Tuners – Locking Tuning Key Pegs Machine Heads Replacement Parts for ST TL Style Electric, Folk or Acoustic Guitars – Nickel

I bought these as part of a project to upgrade a relatively cheap Harley Benton Telecaster. These were far better than the stock tuners and increased the tuning stability, and made the guitar feel more premium. Very happy with them, and very good quality for the price.

Decent quality tuners. Fitted straight in my Harley Benton without issue. Good value and work well

Nice price but not overly smooth, even after some adjusting.

Fitted my Harley Benton T-style perfectly. No drilling or expanding holes required. Perfect upgrade, smooth movement, feel great and locking system works well.

For 20 quid they are a bargain for updating a cheap guitar. Being nickel makes them the cheapest but they are fine. I've had others in the range to and just as good.

I bought these as an upgrade for an £80 2017 Squier Bullet Strat that I’m very fond of, but not quite fond enough of to splash out on Fender items.Firstly I should say that they are a big improvement on the original machine heads, which, whilst functional, were ugly and cheap feeling. The cylinders on these have absolutely no play in them, which is an improvement on the slightly wobbly Squier ones.The only real downsides were:- The feel of the 1st and 6th string heads is different to the middle four, with the middle four having a smoother feel to them. Doesn’t seem to make any practical difference but worth mentioning.- The included screws are really puny and one actually sheared off. I actually ended up reusing the Squier ones.For the money though, they are really good. They feel solid, the locking screws work well and clamp the strings nice and tight with enough knurling on them to get a good grip and they look really good.

Very good quality and look good too

I had initially bought them to replace a set of staggered Wilkinson Easilok machine heads with 8mm holes in the headstock because the thickness of the headstock was burying one of the threading holes in the high E and B strings, being hidden inside the 8mm ferrule. Although these aren't staggered replacements and they have 9mm ferrules, they worked out fine as there was enough depth to maintain reasonable string tension over the nut and avoid using string trees. I left the original ferrules in as the inside diameter of 6mm was the same. The tuners are a little stiff but not uncomfortably so considering they're locking tuners and don't need that many turns. It also means they maintain tuning without slipping. I have a well cut nut that doesn't catch the strings as well as a wilkinson tremelo system that helps to maintain tuning so I know there's no problem with these machine heads. They do their job.
