Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth operation with an improved 1:18 gear ratio. All components are CNC-machined to exacting tolerances and surface-finished, utilizing a self-locking drive mechanism to deliver delicate, stable tuning performance.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine ensures maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tilting moments and removing stress from both the post and rear mounting screw without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 shares identical installation dimensions with its predecessor model, allowing for direct replacement on compatible instruments without headstock modification.
