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.

Simply select the installation plate design that matches the screw/pin hole location of your factory installed machine heads, then follow the three step process described below. You’ll be up and running within about seven minutes
