Ratio Machine Heads

The greatest innovation in machine heads since the tuning peg.

Ratio - Tuned Machine Heads are the first and only machine head to incorporate the different string gauges into the tuning equation.  We balanced the individual gear ratios to each string dramatically simplified the tuning process.  No more overshooting the G string or twisting away on the high E string.  With Ratio, each half key turn equals one semitone change on all strings!  Quicker, more accurate tuning on every string.

What guitars will they fit?

Ratio machine heads fit most major acoustic and electric models in both 3 + 3 and 6 in-line headstock configurations.  We have four button options: Standard, Contemporary, Vintage and Contemporary mini - all with durable triple-plated finishes including chrome, gold, black and nickel.  Unlike other machine heads, Ratio gears are made from hardened steel to precision tune your instrument for years and years.

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.
