Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Designed as an evolution of the iconic closed machine head standard established in 1966, it features state-of-the-art enhancements while preserving its legendary quality.
Each component is CNC-machined and finished for smooth, velvet-like operation and enduring tuning stability. The high-grade brass posts fit precisely within the housing, while self-locking internal mechanics and permanent lubrication with Schaller special grease ensure maintenance-free performance.
Equipped with an innovative stepped flanged washer with a 10 mm diameter, this tuning machine centers the string post securely through the banjo bolt without requiring step-drilled headstock holes. This design relieves lateral tension on both the string post and rear mounting screw for optimal durability.
