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. Continuing the legacy of the original closed tuning machine introduced in 1966, this model incorporates refined innovations while maintaining legendary performance.
Each unit features high-precision CNC-machined components and premium brass string posts engineered for maximum tuning stability and wear resistance. The self-locking drive guarantees smooth, sensitive, and reliable operation, while internal parts come permanently lubricated with Schaller special grease for maintenance-free longevity.
An innovative stepped M6 flanged washer centers the string post through the banjo bolt with solid alignment, eliminating tilting torque and removing mechanical pressure from both the post and mounting screw without requiring stepped peghead holes.
