Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers precise tuning stability and velvety-smooth operation with its refined 1:18 gear ratio. Engineered as a closed-back system, every component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for maintenance-free reliability.
Crafted with precision-fitted brass string posts, these machine heads ensure optimal contact and zero-wear longevity. The stepped M6 flanged washer reliably centers the string post through the hollow screw, removing tilt torque, relieving pressure from mounting screws, and eliminating the need for stepped headstock drillings.
Designed to mount seamlessly as a drop-in replacement without modifications, the M6 180 provides self-locking drive precision across diverse electric and acoustic headstock configurations. Complete with required mounting hardware, it ensures effortless installation and rock-solid intonation.
