    Great solution for my new PRS SE NF3

    I purchased a PRS SE NF3 a couple weeks ago. It is a great guitar, but wanted a locking tuner upgrade. I was originally nervous about the price combined with the "universal fit" thing. I took a chance and ordered these and they have been awesome. The universal plates fit great, although I did have to put in the plates for 3 and 4 together as they are butted up to one another. I was able to use the same screws, but new ones were also provided. I am attaching a photo.

    Regarding the "Ratio" feature, it is a game changer. I never expected it to feel different, more accurate, from other tuning heads. But these being geared to each string's thickness/tension is really effective.

    If you're on the fence, I hope this helps. This is a unique product with features I would love to see become more standard from premium guitar companies. I am not considering upgrading my Telecaster to Ratio tuners.

    Worth the $$$

    I’m glad I threw frugality to the wind and bought these tuners. They really are a worthwhile upgrade. EBMM guitars are very stable tuning wise, but the Ratio heads make getting there so much easier!

    Great addition

    This was an easy swap to upgrade to locking tuners. Excellent quality and tuning stability seems rock solid so far.

    Ideal LTD/ESP solution.

    These Ratio tuners are the absolute best drop-in solution for LTD/ESP tuning issues. Simple and quick to install, without the adaptive templates, and the tuning results are exceptional. I use a strobe bench tuner, and these machine heads yielded the most accurate results that I've ever seen. Highly recommended.

    Installed on an LTD EC-1000 Deluxe, as shown in photo.
