Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability. Featuring an optimized 1:18 gear ratio, this closed tuner provides delicate, reliable adjustments for high-performance tuning comfort.
Crafted with CNC-machined components and premium brass string posts fitted directly into the housing, the M6 135 minimizes wear while maximizing tuning retention. The innovative stepped flanged washer centers the post securely and eliminates tilting torque without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for maintenance-free operation, this model matches the original mounting dimensions of predecessor units for direct, modification-free replacement.
