Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering ultra-smooth and accurate tuning performance. Setting the benchmark for enclosed tuning machines since 1966, this updated model integrates modern innovations while preserving its iconic aesthetic and reliability.
Crafted with CNC-machined components and premium brass string posts fitted directly into the housing, the M6 180 ensures exceptional tuning stability and virtually wear-free operation. Internal self-locking mechanisms and permanent lubrication with Schaller specialized grease guarantee completely maintenance-free functionality.
Featuring the innovative stepped M6 flanged washer, this design securely centers the string post via the banjo bolt with a 0.39 in diameter step, eliminating tilting torque and removing the need for a stepped peghead bore. It offers direct, hassle-free replacement compatibility on modern and classic guitar headstocks.
