Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers precision engineering and reliable tuning stability. Built with a refined 1:18 gear ratio, it ensures smooth, accurate adjustments across various musical styles and performance demands.
Crafted with high-precision CNC-machined components and premium brass string posts, each closed-type tuner is permanently lubricated with Schaller special grease for maintenance-free operation. The stepped M6 flanged washer centers the post securely, eliminating tilting torque without requiring stepped headstock drilling.
Featuring the exact installation dimensions of its predecessor, the M6 135 serves as a direct, modification-free replacement. It is available in various configurations, including standard, Locking, and TopLocking mechanisms to fit standard and slotted headstocks.
