Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine features a 1:18 gear ratio that delivers precise, smooth, and dependable tuning stability. Engineered with high-precision CNC-machined components and self-locking drive technology, it ensures velvety response and consistent performance.
Equipped with premium brass string posts precisely fitted to the housing, this tuning machine provides maximum wear resistance. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock drilling, eliminating tilt torque and protecting structural components.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 135 shares identical installation dimensions with its classic predecessor for direct, modification-free replacement on compatible guitar headstocks.
