Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 tuning machine sets a benchmark for enclosed tuning mechanisms, combining legendary heritage with modern precision engineering. Built with a refined 1:18 gear ratio, it ensures velvet-smooth operation, fine sensitivity, and tuning stability for demanding players.
Every component is precision CNC-machined and surface-treated, featuring high-grade brass posts meticulously fitted into the housing for wear-free performance. The self-locking drive and lifetime lubrication with specialized grease provide maintenance-free reliability.
Equipped with an innovative stepped flanged washer with a 0.39 in (10 mm) base diameter, this design accurately centers the string post via the banjo bolt and eliminates tilting torque. It retains identical installation dimensions to its predecessor for direct replacement without instrument modifications.
