Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machines set a high standard for closed tuning systems, featuring an improved 1:18 gear ratio for exceptionally precise and smooth tuning comfort. Each component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation and lasting durability.
Equipped with high-grade brass string posts engineered for maximum tuning stability, these machine heads incorporate the innovative stepped M6 flanged washer. This design feature centers the string post securely through the banjo bolt, preventing tipping torque and eliminating the requirement for stepped headstock drilling.
Designed as a direct replacement for legacy closed tuners, the M6 180 seamlessly retrofits standard headstock configurations without modifications. It delivers rock-solid performance, fine-touch adjustability, and reliable holding power for discerning guitarists.
