Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an evolution of the iconic closed-housing tuner first introduced in 1966. Engineered with a precise 1:18 gear ratio, it delivers velvety-smooth action, exact micro-adjustments, and exceptional tuning stability.
Every component is precision CNC-machined and surface-finished, featuring high-grade brass string posts engineered for wear-free durability. The innovative stepped M6 flanged washer centers the string post securely without requiring stepped peghead drilling, eliminating tilting torque and protecting mounting hardware.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 180 serves as a direct, drop-in replacement for earlier M6 models without headstock modification.
