Review: Awesome Value for the Money - Great tuners for the money. I got these for Christmas a few years ago and swap them out on an ES 335 copy that I had it made a world of difference plus it gave it that Les Paul custom type of feel instantly changing the image on the guitar. The installation was extremely easy and they dropped right into the old slots. All of the hardware was included, and all of the screw heads worked perfectly fine. I highly recommend when you lock the tuners that you tighten the wheel additionally, as it does seem to make a difference in really locking in that particular string.
Review: Best Value Locking Tuners - Installed on an Epiphone SG Muse. Smooth and very progressive with little slack or snatch. Beautifully finished in chrome. Great upgrade. Heavier than non locking tuners but that is to be expected unless you want to spend a £100++ on Hipshot tuners? Work out at £5 each for six and are brilliant value at that price. I can't fault them. QC? Maybe an issue but the set I received were perfect. Highly recommend these as an upgrade for Epiphones and there's no need to drill holes either - at least not on my Epi model.
