Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin Guitar Tuning Machine features an advanced 1:18 gear ratio, delivering smooth tuning precision and exceptional pitch stability. Engineered with high-precision CNC-machined components and self-locking drive technology, these closed tuning machines ensure consistent, sensitive adjustments with zero backlash.
Crafted with premium brass string posts fitted precisely into the housing, each unit offers maximum wear resistance and longevity. The innovative stepped M6 collar washer eliminates the need for stepped headstock peg holes, centering the string post securely and removing tilting torque from the mounting assembly.
Permanently lubricated with Schaller special grease, these maintenance-free tuning machines feature a dual-pin mounting configuration designed for straightforward drop-in installation on compatible solid headstocks.
