Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers refined performance and unmatched tuning precision with its advanced 1:18 gear ratio. CNC-machined components and premium brass posts ensure velvety smooth action, long-lasting wear resistance, and exceptional tuning stability. Each enclosed tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring the innovative stepped M6 flanged washer, this tuner simplifies installation while ensuring rock-solid, centered alignment of 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.
Designed as a direct replacement for legacy closed tuners, the M6 180 easily drops into existing installations without modifications. High-grade materials and fine finishing make this tuning machine an ideal upgrade for demanding guitarists seeking precision and durability.
