Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, delivering unmatched tuning accuracy and smooth operation. Engineered with an upgraded 1:18 gear ratio, it provides ultra-precise, velvet-smooth adjustments backed by a self-locking drive mechanism for maximum tuning stability.
Every component is precision CNC-machined and surface-treated, featuring high-grade brass string posts meticulously fitted into the housing to eliminate wear. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tipping torque and removing the need for a stepped headstock hole.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 135 shares identical mounting dimensions with its predecessor model, allowing direct, modification-free retrofits on standard instruments.
