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.

    Great!!

    This might be obvious, but when installing, put the tuner into the plate before putting the screws into the headstock plates. If you put the screws into the plates first the tangs of the tuner might not fit well into the plate. The work wonderfully when installed.

    Amazing as always!

    Every guitar I put these on, it just makes it perfect. Much easier to change strings. The feel of the tuning needle slowing down in time and being able to tune with pin-point precision is just excellent.
