Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and legendary performance. Featuring an enhanced 1:18 gear ratio, it ensures precise, smooth, and velvety tuning with exceptional pitch stability. High-precision CNC-machined components and self-locking drive mechanics provide consistent tuning control for various guitar setups.
Crafted with premium brass string posts fitted seamlessly into the housing, these tuners resist wear while maintaining high tuning integrity. The innovative stepped M6 flanged washer eliminates tilt torque and centers the string post perfectly via the banjo bolt, eliminating the need for step-drilled headstocks and protecting both the post and mounting screws.
Featuring the exact installation dimensions of its predecessor, the M6 135 serves as a direct, modification-free replacement. Sealed and permanently lubricated with specialized Schaller grease, these maintenance-free tuning machines deliver durable, long-lasting reliability across all playing environments.
