Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry standard with its enhanced 1:18 gear ratio, delivering precise, velvety-smooth tuning and exceptional stability. All components are high-precision CNC-machined and surface-treated, featuring a self-locking drive mechanism that guarantees smooth, reliable performance.
Crafted with premium brass string posts fitted accurately into the housing, this machine head provides maximum tuning stability and wear resistance. Closed-gear construction with permanent internal lubrication ensures maintenance-free operation under rigorous playing conditions.
The innovative stepped M6 flanged washer centers the string post reliably via the hollow screw without requiring stepped headstock drilling. This design eliminates tilting torque and reduces mechanical strain on both the string post and rear mounting screw for lasting durability.
