Perfect pitch black (see what I did here?)
Best tuners on the market, no contest, competition is not even close.
Quality on par with the best of the best, functionality is better.
Used 7 string set for B standard tuned (13-64 strings) Jim Root Jazzmaster and skipped number 4 tuner (d string)
So I installed 7-6-5-3-2-1. I could use #4 tuner for 13 gauge string, but because it’s staggered it’ll be taller than #2 tuner post.
I find most benefit of ratio tuners are on wound strings so you don’t have to do 1/360th turns on thick gauge anymore.
Installation took like 3 minutes on top of restring, black fender plates = no drilling and great angle behind nut due to ever so slightly reduced post height.
2 main downsides of ratio tuners:
1. Price bites.
2. You want them on ALL YOUR GUITARS after trying once. Both downsides combined get pricey real fast.
Only guitar I wouldn’t install ratio tuners is one with evertune bridge. Regular lockers are enough there.
