Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and velvety-smooth operation with an advanced 1:18 gear ratio. Continuing the legacy of the original closed-housing benchmark introduced in 1966, this updated edition features high-precision CNC-machined components with a self-locking drive that provides consistent, sensitive, and wear-free stability.
Crafted with premium brass string posts precision-fitted into the housing, the unit features the innovative stepped M6 flanged washer with a 0.39-inch diameter base. This design centers the string post securely through the hollow screw without requiring stepped peghead drilling, eliminating tilting torque while relieving mechanical stress from both post and mounting screw.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 180 features slightly smaller outer housing dimensions than its predecessor for straightforward drop-in retrofits without headstock modification. Each unit delivers dependable performance for standard, locking, and slotted headstock configurations.
