Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for sealed tuners, featuring an advanced 1:18 gear ratio that delivers precise, velvety-smooth tuning stability. Every component is CNC-machined and surface-treated to guarantee long-lasting performance and consistent, wear-free action.
Equipped with high-grade brass string posts engineered specifically for exact housing fitment, this tuner prevents string slippage and ensures optimal mechanical integrity. The innovative stepped M6 flanged washer centers the post automatically without requiring stepped headstock drilling, eliminating tilt torque and relieving pressure from mounting screws.
Featuring permanently lubricated internal gearing with specialized grease, the M6 135 offers completely maintenance-free operation over its lifespan. It shares identical mounting dimensions with its classic predecessor, allowing for seamless direct-fit replacements and effortless upgrades on standard headstocks.
