The Simple Genius Behind The Ratio® Tuned Machine Heads is it's utilization of its patented multi-gear technology. Every string on your guitar responds differently to tension. In other words the plain G string jumps in pitch to small amounts of tension while the D string (with a thinner core) requires more turns on the machine head to get the same pitch change.

Graph Tech has tuned the gear ratios to each string position so that every string responds the same to any tuning adjustment anywhere from 12:1 to 39:1 gear ratio. It's as dramatic as switching from a manual transmission on a car to an automatic. No more thinking about which string you are tuning! With Ratios, one turn is about one tone change on every string, making tuning, retuning and open tunings easier, quicker and more intuitive.

Predictable, Precise Tuning, Retuning and Open Tunings
Ratio® tuning feels natural. You don't have to think about which string you are tuning because they all feel and 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.

Worth every penny!


Easy to install, didn't realize these were locking tuners. Fast restring and I've never seen my tuner needle move more stable. I'll put Ratios on all my guitars



Ratio Turners are amazing!


I put them on an old Alvarez acoustic-electric just to see what they would be like. Not only was I impressed by the locking aspect of the tuners (I've never had locking tuners before), but the responsiveness of the tuners to each string is amazing. They look great, feel great, work great, and the price was well below what some other companies charge for locking tuners.
