Independent shopping perspective
The Korena take
The black chrome Grover Locking Rotomatics 106 Series is built around an 18:1 ratio and an internal locking cam. Feed a string through, pull it taut by hand, then turn the peg; the cam engages as you tune. That puts the task on tuning by ear rather than separately locking the string. Grover states that the locked machine heads hold tune under heavy playing conditions, and identifies installation in existing peghead holes as the intended upgrade path.
Strong match
Who this is for
- Tuning by ear after feeding strings through and pulling them to hand tension.
- Guitars with existing peghead holes intended for these 106 Series tuning machines.
