Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed with high-precision CNC-machined components and a self-locking drive, it provides consistent, delicate adjustment and reliable tuning stability.
Crafted with premium brass string posts precision-fitted into the housing, this sealed tuning machine is permanently lubricated with Schaller special grease for completely maintenance-free performance. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moment and preventing wear without requiring a stepped peghead bore.
Featuring the exact installation dimensions of its classic predecessor, the M6 135 serves as a direct drop-in replacement without requiring headstock modifications. It ensures superior mechanical longevity and effortless string tension management for professional instruments.
