Independent shopping perspective
For a 3+3 guitar, this Gold Grover 406 Series set combines mid-size buttons with locking Rotomatics operation. String loading is straightforward: thread the string through the hole, pull it hand-tight, and begin tuning. Turning the knob first engages the locking cam; after the string is secured, the post rotates to take it to pitch. Grover specifies less than one full rotation to reach pitch and an 18:1 ratio for precision tuning.
