The Grover 409 Series Vintage A Style tuning machines provide precision tuning for your mandolin. With an 18:1 gear ratio, you'll achieve accurate tuning for consistent intonation and tone. The open worm gear configuration and die-cast plate give these tuners a vintage aesthetic while maintaining sturdy construction. The bell-shaped button screws continue the retro styling. These tuners drop into most mandolins so you can upgrade your instrument with premium components that keep it in tune through hours of playing.
