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. 

Ratio InvisoMatch Mounting Plates are the easiest approach to installing Ratio Tuned Machine Heads on your guitar. 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
