Independent shopping perspective

The Korena take

Gold-finished Grover 406 Series tuning machines in a reverse 6-in-line layout. The locking design changes the order of operation during tuning: after the string is passed through the hole and pulled hand-tight, the cam rotates to lock it, then the string post begins turning. That lets the post bring the string to pitch in under a full rotation. Smaller buttons and 18:1 gearing complete the mid-size Rotomatics format.
