Ratio - Tuned Machine Heads incorporate different string gauges into the tuning equation. From Low E to High E 39:1, 24:1, 20:1, 14:1, 20:1, 12:1. Graphtech has balanced the gear ratios to each string simplifying the tuning process. With Ratio, a half turn is a semi-tone! Every string reacts the same to any tuning adjustment. Predictable, precise tuning on every string.
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. 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..
Note: Packaging may differ, Graph Tech has changed packaging on many Ratio Tuners
