GroverProfessional Mandolin A Style 409 Series Pearloid Button Tuning Machines Gold
Independent shopping perspective
The Korena take
Made for mandolin, Grover’s 409 Series machine heads combine a gold finish with pearloid buttons and vintage-leaning visual details. The adjustable worm gear and die-cast plate are engineered to keep the worm and gear centerlines aligned for precise tuning. An 18:1 ratio gives very fine pitch control, while the open gears use a modern worm-over arrangement for quick, straightforward tuning. Bell-top button screws complete the period-style presentation.
