Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents high-precision engineering for stringed instruments, establishing a benchmark in tuning accuracy and stability. Built with a refined 1:18 gear ratio, this enclosed tuner delivers smooth, velvety operation and sensitive response. High-grade brass string posts fit tightly into the housing to minimize wear and maximize long-term tuning retention.
Every component is precision CNC-machined and finished for consistent, self-locking drive performance. An innovative stepped M6 flanged washer reliably centers the string post through the threaded bushing without requiring stepped headstock holes, eliminating tilt torque and relieving stress on mounting hardware. Sealed internal gearing is permanently lubricated with specialized Schaller grease for maintenance-free operation.
Designed with standard 180-degree mounting tab geometry, the M6 180 allows straightforward installation and direct replacement on solid or slotted headstocks without structural modifications. Its robust housing and premium internal mechanics provide exceptional reliability for professional performance and rigorous playing conditions.
