Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Engineered with CNC-machined components and surface-finished parts, it utilizes a self-locking drive mechanism to ensure sensitive, uniform, and reliable tuning stability.
Equipped with high-grade brass string posts precision-fitted into the housing, this enclosed tuner features permanent Schaller special grease lubrication for maintenance-free performance. The innovative stepped M6 flanged washer centers the post reliably without requiring a stepped peghead bore, eliminating tilting torque and reducing stress on mounting hardware.
Featuring the exact installation dimensions of its predecessor model, the M6 90 allows for direct drop-in replacement without instrument modifications. Its durable construction and precision engineering make it an ideal upgrade or replacement component for discerning guitarists.
