Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for exceptionally smooth, precise, and stable tuning comfort. CNC-machined components with premium surface finishing and self-locking drive mechanisms provide consistent, fine-tuned performance without wear.
Crafted with durable high-grade brass string posts precision-fitted into the housing, this tuner incorporates an innovative stepped flanged washer with a 0.39-inch diameter base. This design reliably centers the post without requiring stepped headstock boreholes, effectively eliminating tilting torque and reducing pressure on both the post and mounting screws.
Featuring identical installation dimensions to its classic predecessor, the M6 135 allows direct, modification-free retrofitting. Every enclosed unit comes permanently lubricated with Schaller special grease for entirely maintenance-free operation and supreme tuning stability.
