Graphtech PRL-8311-B0 Machine Head 3+3 Locking Tuners Black for electric or acoustic guitar

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 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..

NOT JUST ANOTHER MACHINE HEAD.

Ratio is more than just another entry into the machine head market. Instead, Ratio has reinvented how machine heads function with the musician.

RATIO patented gear technology
RATIO – Calibrated Machine Heads incorporate different string gauges into the tuning equation.

From Low B to High E 48:1, 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.
