Graph Tech Ratio Electric Locking 6-In-Line Tuned Machine Heads, Chrome

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.
