Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry standard for enclosed tuners, featuring an upgraded 1:18 gear ratio that provides velvety-smooth operation and precise tuning stability. Each component is precision CNC-machined and finished to deliver consistent performance through its self-locking drive mechanism.
Equipped with premium brass posts fitted directly into the housing, these tuners ensure maximum wear resistance and rock-solid pitch retention. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilt torque and protecting headstock mounting points without requiring stepped peghead drilling.
Permanently lubricated with specialized Schaller grease for maintenance-free longevity, the M6 135 shares identical installation dimensions with predecessor models for direct, seamless replacement on compatible electric and acoustic guitar headstocks.
