Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for velvet-smooth, precise tuning action. Each component is precision CNC-machined and finished to deliver seamless, slip-free performance and exceptional tuning stability.
Engineered with high-grade brass string posts precisely fitted into the housing, this tuning machine eliminates wear and provides long-lasting reliability. The innovative stepped M6 collar washer ensures secure centering of the post via the banjonut, eliminating tilting torque and protecting the headstock without requiring stepped drilling.
Permanently lubricated with Schaller special grease, the sealed design remains completely maintenance-free over years of use. It shares identical mounting dimensions with its classic predecessor, allowing for direct replacement and hassle-free upgrades on standard headstocks.
