Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets a benchmark for closed-type tuners, delivering an improved 1:18 gear ratio for exceptionally precise and smooth tuning control. Crafted with CNC-machined components and high-grade brass posts fitted into the housing, it ensures outstanding tuning stability, fine adjustments, and wear-free performance.
Equipped with an innovative stepped flanged washer, this tuning machine simplifies headstock installation by securely centering the string post via the banjo bolt. This specialized design eliminates tilting torque and reduces direct mechanical pressure on both the post and the rear mounting screw without requiring stepped headstock boreholes.
Each closed mechanism is permanently lubricated with Schaller special grease for completely maintenance-free operation. Engineered for direct drop-in replacement, it fits seamlessly onto compatible headstocks while maintaining classic aesthetic proportions and superior reliability.
