About This Item

Faster and more accurate tuning
Optimized gear ratios for each string means tuning your guitar has never been easier.

Multi-geared tuning technology
The Graph Tech team tuned the gear ratios to each string position so that every string responds the same to any tuning adjustment. You get fine tuning on the thicker core strings and coarser tuning on the thinner core; anywhere from 12:1 to 39:1 gear ratio. With Ratio, one turn is about one tone change on all strings, making tuning, retuning and open tunings easier, quicker and more intuitive.

Predictable, precise tuning
Ratio tuning just feels right. You don't have to think about which string you are tuning because they all respond the same. No more overshooting the Low E or G. No more twisting away on the High E or D string. Open tunings have never been easier. String gauges such as light top, heavy bottom are no problem with Ratio; they still do the same precision tuning.

Don't sweat the small gears
Double-envelope gears made of hardened steel provide enhanced durability and ultra-smooth response for the high ratio gears.

Triple plated chrome finish with contemporary buttons.

Part Two - Staying in Tune


Verified Buyer

Now that I have had my tuners in place for a couple of days I am noticing that the guitar is staying in tune much better than before and that the geared tuners do make fine adjustment easier than regular tuners, even for the B String! Bravo Graph Tech!


Easy Installation! Beautiful Fit & Finish


Verified Buyer

Just received these tuners yesterday and installed them on my Eastman Archtop. The included mounting plates made the task very easy and they look great! Haven't had enough time to comment on their geared tuning feature and the numbers on the tuners indicating position are quite small so turn on the lights and get out your magnifying glass!
