$168.08Price
The Schaller M6 90 guitar tuning machine represents the pinnacle of precision tuning, featuring an improved 1:18 gear ratio for smooth, accurate adjustments. CNC-machined components and self-locking drive mechanics ensure dependable tuning stability and sensitive operation.
Equipped with high-grade brass string posts and permanently lubricated with Schaller special grease, these sealed tuners are built for completely maintenance-free performance. The stepped M6 flanged washer centers the post reliably without requiring stepped peghead drilling, eliminating tilting torque.
Featuring the exact installation dimensions of its classic predecessor, the M6 90 allows for direct replacement on solid or slotted headstocks without modification.
