GROVER Mid-Size Locking Rotomatics 406 Series Tuning Machines Black Chrome 6-in-line

The Grover mid-size locking Rotomatics 406 series tuning machines give you precision tuning for 3+3 and reverse 6-in-line guitar. You get the same innovative engineering and classic design as the standard locking Rotomatics, but with smaller buttons sized perfectly for your instrument. Simply insert each string through the string hole, pull it to tension by hand and begin tuning. As you start turning the knob, only the locking cam in the string post rotates. Once the string is locked in tune, the string post starts turning, allowing you to quickly bring each string to pitch in less than one full rotation. With an 18:1 gear ratio, you'll stay in tune through even the most intense practice sessions and performances.
