Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and tuning stability, featuring an improved 1:18 gear ratio for smooth, accurate adjustments. Originally setting the global standard for enclosed tuning machines in 1966, this updated edition incorporates modern CNC manufacturing and premium surface finishing.
Equipped with solid brass string posts precisely fitted to the housing, each tuning machine ensures minimal wear and reliable performance. The innovative stepped M6 flanged washer centers the post securely through the banjo bolt without requiring stepped headstock drilling, eliminating tilt torque and relieving pressure from the post and mounting screw.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 135 matches the exact installation dimensions of its predecessor for straightforward replacement and installation.
