GroverMid-Size Locking Rotomatics 406 Series Tuning Machines Chrome 3+3
Independent shopping perspective
The Korena take
Built as a locking tuning-machine set for 3+3 and reverse six-in-line guitars, these mid-size 406 Rotomatics use smaller buttons than standard locking Rotomatics. Feed a string through its hole, draw it hand-tight, then turn the knob: the locking cam moves first, and the post begins turning after the string locks. Each string can reach pitch in less than one full rotation. The 18:1 ratio provides precise tuning adjustment.
Strong match

Product questions
Before you decide

01How does the locking action work?
After the string is inserted and pulled hand-tight, turning the knob rotates the locking cam first. Once locked, the string post turns to bring the string to pitch.
