Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 Guitar Tuning Machine delivers exceptional tuning precision and stability with its refined 1:18 gear ratio. Engineered with CNC-machined components and surface-finished housings, it provides a smooth, sensitive tuning experience backed by a self-locking drive mechanism.
Featuring high-grade brass string posts precisely fitted into sealed housings, each unit is permanently lubricated with Schaller special grease for maintenance-free operation. The innovative stepped flanged washer centers the string post securely without requiring stepped headstock drillings, effectively eliminating tilting moments.
Maintaining identical mounting dimensions to its classic predecessor, the M6 90 allows for direct, seamless replacement without instrument modification. High-precision manufacturing ensures wear-free longevity and dependable pitch retention for professional musicians.
