Graph Tech's Ratio Locking 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 Locking Tuned Machine Heads.
