Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 series tuning machine sets a benchmark for closed guitar tuners, featuring an upgraded 1:18 gear ratio for smooth, precise, and dependable tuning stability. Engineered with high-precision CNC-machined components and self-locking drive mechanisms, it delivers exceptional control and long-lasting durability.
Crafted with premium brass posts fitted directly into the robust housing, these tuners are pre-lubricated with specialized grease for completely maintenance-free operation. The stepped flanged washer centers the string post securely over the threaded bushing, eliminating tilting torque and reducing stress on mounting screws without requiring stepped headstock drilling.
Designed as a direct drop-in replacement for earlier models, the M6 180 installs seamlessly on solid and slotted headstocks alike. Every set delivers professional-grade string anchoring and reliable intonation retention for discerning musicians and custom instrument builders.
