    Quality!

    I have the Ratio Machine Heads on all my guitars, some locking and some non-locking. Electric or acoustic, they work great, the adapters (when needed) fit right, after years not one failure of any kind. A quality product that works as advertised, maybe better. Love them!

    Works perfectly on my Taylor GS Mini E-Koa

    I know a lot of people think it is overkill to put locking tuners on an acoustic. There is no tremolo bar and not a lot of big string bends, but the stability and the ease of string change make it worth it in my opinion. I installed the PRL-8411's on my new Taylor GS Mini e-Koa. The machine heads matched perfectly with the two original holes on the back of the head. No need for any InvisoMatch plates. The individual ratios for each string makes tuning much quicker and locks in accurately. Highly recommended.
