Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers precise tuning comfort and stability with an upgraded 1:18 gear ratio. Engineered with high-precision CNC-machined components and surface finishes, it features a self-locking drive that ensures consistent, responsive performance across all playing conditions.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine provides maximum wear resistance and pitch retention. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moment and relieving stress without requiring stepped headstock drilling.
Permanently lubricated with specialized grease for maintenance-free operation, the M6 135 shares identical mounting dimensions with its predecessor model for seamless replacement. Available in locking and standard configurations, it offers customizable buttons and posts to suit your exact guitar specifications.
