Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers exceptional tuning accuracy and smooth operation with its refined 1:18 gear ratio. All components are CNC-machined to precise tolerances and surface-finished, featuring a self-locking drive mechanism that ensures stable and delicate adjustments.
Equipped with high-grade brass string posts engineered for wear-free durability, each unit maintains superior tuning stability. The stepped flanged washer provides dependable centering without requiring stepped headstock boreholes, effectively eliminating tilting torque and protecting the mounting hardware.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 90 shares the standard installation dimensions of its predecessor for direct, seamless replacement on compatible headstocks.
