THE SIMPLE GENIUS
BEHIND RATIO® SYNCHRONIZED MACHINE HEADS
Ratio machine heads are calibrated to the core thickness of each individual string—meaning that you get fine tuning for thicker-core strings, and coarser tuning on thinner-core strings via gear ratios from 12:1 to 39:1. Every string feels and reacts the same to your tuning adjustments. With Ratio®, one turn is about one tone change on all strings, making tuning, retuning and exploring open tunings easier, quicker and more intuitive.
PREDICTABLE, PRECISE TUNING AND RETUNING
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 plain G. No more twisting away on the High E or D string. Retuning to explore open tunings has never been easier. In addition, using popular light top, heavy bottom string gauges are no problem with Ratio®, as each string gets the same precision tuning.
NOT JUST ANOTHER MACHINE HEAD
Ratio® machine heads make tuning a pleasure. Every time you turn a Ratio® machine head it feels natural, easy, and intuitive. Now, you can experience the performance-enhancing Ratio® technology on vintage instruments. Stay Retro but don't tune your guitar like it's 1957!
