Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision and comfort with an advanced 1:18 gear ratio. Designed with high-precision CNC-machined components and surface finishes, it provides self-locking, smooth, and highly stable tuning performance. High-grade brass string posts fit securely into the housing to ensure wear-free longevity and exceptional tuning stability.
Featuring the innovative stepped M6 flanged washer with an outer diameter of 0.39 in (10 mm), this tuning machine reliably centers the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the string post and rear mounting screws. All enclosed tuners are permanently lubricated with Schaller special grease for maintenance-free operation.
Sharing identical mounting dimensions with its predecessor model, the M6 135 allows for seamless, direct replacement without headstock modifications. This versatile tuning machine is available across multiple housing finishes, button configurations, and post locking options.
