Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding tuning precision and velvety-smooth operation with its refined 1:18 gear ratio. Engineered with high-precision CNC-machined components and surface finishes, the self-locking drive ensures consistent, sensitive, and stable tuning performance.
Featuring solid brass posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear-free longevity. The innovative stepped M6 flanged washer centers the string post reliably without requiring stepped peghead counterbores, effectively eliminating tilting torque and reducing mechanical stress.
All enclosed housings are permanently lubricated with proprietary Schaller special grease for completely maintenance-free reliability. Designed with dimensions compatible with original M6 housings, it allows straightforward, modification-free upgrades and replacements on standard headstocks.
