Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers high-precision tuning stability with an enhanced 1:18 gear ratio. CNC-machined components and high-grade brass string posts provide smooth operation, reliable self-locking performance, and long-term durability.
An innovative stepped M6 flanged washer centers the string post accurately without requiring a stepped peghead bore, effectively eliminating tilting torque and protecting the mounting hardware. The fully enclosed housing is permanently lubricated with Schaller special grease for completely maintenance-free performance.
Designed as a versatile drop-in replacement, this tuner fits modern instruments and serves as an upgrade over original M6 units without requiring headstock modifications. Premium materials and precise manufacturing ensure robust tuning retention across diverse configurations.
