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. Review: Second Pair and it's GREAT! - 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! ## Features - Package includes: 6 pieces (3 for Right, 3 for Left Hand) locking guitar tuners pegs, 6 mounting screws, 6 threaded bushings, and 6 ferrules, good replacement for almost electric or acoustic guitars. - Guitar sealed tuning machines with heavy duty internal gear, sturdy and convenient. Easy to install, easy to replace your old or dirty guitar tuning pegs. - Guyker locking tuners help to provide finer tuning and greater stability. - Hexagonal shaped button with sealed housing and 45 degree fixing tag. - Gear Ratio - 1:21, designed to fit modern 10mm headstock holes.
