Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an evolution of the iconic closed tuner design, engineered with a refined 1:18 gear ratio for precise and ultra-smooth tuning accuracy. High-precision CNC-machined components and surface finishes pair with a self-locking drive to ensure uniform, sensitive adjustment and exceptional tuning stability.
Crafted with premium brass string posts precisely fitted into the housing, this machine head prevents wear and guarantees lasting performance. The innovative stepped M6 flanged washer centers the string post securely via the hollow screw, removing tilt torque and eliminating the need for a stepped peghead bore.
Permanently lubricated with specialized Schaller grease, each enclosed unit provides completely maintenance-free operation across years of play. The refined housing geometry allows straightforward replacement of legacy M6 units without requiring headstock modifications.
