Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision and stability with an enhanced 1:18 gear ratio for smooth, sensitive tuning. Crafted with CNC-machined components and high-grade brass string posts, it ensures consistent operation, maximum wear resistance, and reliable performance.
Featuring the innovative stepped M6 flanged washer, this machine head automatically centers the post via the banjonut, eliminating tilt and removing excess pressure from both the post and mounting screw without requiring stepped peghead holes. All enclosed housings come permanently lubricated with specialized grease for maintenance-free longevity.
Sharing identical installation dimensions with its classic predecessor, the M6 135 allows direct, drop-in replacement without instrument modifications. Available in various housing finishes, button configurations, and post variations to fit solid or slotted headstocks.
