Faster and More Accurate Tuning for Your Acoustic

Graph Tech's Ratio Acoustic Tuned Machine Heads offer a revolutionary new experience in ensuring your guitar is tuned more quickly and accurately than conventional tuner designs. Each tuner in the set boasts a custom gear ratio that makes each machine head react the same — roughly one full turn per whole tone. Because each string reacts the same, not only is tuning a more pleasant experience, but nailing alternate tunings is a much faster process. Graph Tech's mission statement is, "To Improve Your Playing Experience." They've nailed it with the Ratio Acoustic Tuned Machine Heads.

Graph Tech's Ratio technology

Though it's a simple idea, Graph Tech's Ratio technology completely changes the way you tune your guitar. All six strings are outfitted with gear ratios that ensure you attain the same response from your wound low E string as you do your unwound high E. No matter what string you are tuning, you'll notice that one full turn of the tuner equates to roughly one whole tone pitch change. The Ratio technology makes nailing your pitch much easier and faster. And the Ratio Acoustic Tuned Machine Heads also work great on electric string sets with a wound G string.

Easy installation with no drilling

One of the greatest benefits of the Ratio Acoustic Tuned Machine Head system is that they install onto your guitar's headstock without any drilling or other destructive procedures and are completely reversible. Graph Tech's InvisoMatch mounting plates ship with the tuners. The machine heads mount directly to those plates and aren't screwed into your instrument. As their name would suggest, the InvisoMatch mounting plates are completely hidden by the Ratio Acoustic Tuned Machine Heads and offer a sleek, low-profile look.
