RATIO® patented gear technology
RATIO® - Calibrated Machine Heads incorporate different string gauges into the tuning equation.
From Low E to High E 39:1, 24:1, 20:1, 35:1, 20:1, 12:1.
We 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.
