Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers refined tuning precision and velvety-smooth operation with its improved 1:18 gear ratio. CNC-machined components and high-grade brass string posts ensure exceptional tuning stability, long-term wear resistance, and reliable performance.
Featuring the innovative stepped M6 flanged washer with a 0.39-inch diameter base, this tuner reliably centers the string post via the banjo bolt without requiring a stepped headstock bore. This design eliminates tilting torque and absorbs mechanical pressure from both the post and mounting screws.
Equipped with permanent Schaller special grease lubrication, the enclosed housing is entirely maintenance-free. It serves as a direct, modification-free replacement for previous M6 iterations, bringing modern mechanical precision to any compatible electric or acoustic guitar.
