$110.99
The Grover 406C Mini Locking Rotomatic® tuning machines combine the legendary performance of Grover Rotomatics with the convenience and stability of a locking tuner system. Designed for players who demand fast string changes, superior tuning stability, and precise adjustment, these tuners feature Grover’s innovative internal cam-post locking mechanism. Unlike traditional locking tuners that require thumbwheels or locking knobs, the 406C automatically locks the string as you begin tuning. Simply insert the string through the post, pull it tight by hand, and turn the tuner. The internal cam locks the string securely before the post begins winding, allowing the guitar to reach pitch in less than one full revolution of the string post. Featuring a high-precision 18:1 gear ratio, enclosed permanently lubricated gear housings, and Grover’s renowned build quality, the 406C provides smooth tuning action, exceptional accuracy, and long-term reliability. The compact mini-button design offers a streamlined appearance while maintaining excellent functionality.
