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.
