Tuning innovation for quick, accurate and consistent pitch.
The Grover locking Rotomatics 106 series tuning machines give you precision tuning and rock-solid stability. With an 18:1 gear ratio, you can dial in your instrument with precision in less than one revolution. Once locked in, these machine heads hold tune even under heavy playing conditions. Simply feed your strings through, pull to tension by hand and begin tuning—the internal cam locks automatically as you turn the peg, allowing you to focus on tuning by ear. Drop these tuning machines into your existing peghead holes for an instant upgrade in performance and style. For guitarists seeking professional-level tuning stability and control, the 106 series delivers.
