Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Continuing the legacy of the original closed-type tuner introduced in 1966, this model incorporates refined mechanical precision without losing its iconic identity.
Every component is CNC-machined to exacting tolerances and surface-treated for maximum durability, while the self-locking drive ensures uniform and stable tuning. The high-grade brass string posts are precision-fitted into the housing to guarantee wear-free performance and superior tuning stability over extended playing time.
Featuring an innovative stepped flanged washer with a 0.39 in diameter, the M6 180 centers the string post through the banjonut and eliminates tilting forces on the mounting hardware. All closed gear housings are permanently lubricated with specialized Schaller grease for completely maintenance-free operation.
