Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability with an improved 1:18 gear ratio. CNC-machined components and high-grade brass string posts provide wear-free performance and precise adjustments.
Featuring the stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the banjo bolt and eliminating the need for a stepped peghead bore. It also absorbs lateral pressure from both the post and mounting screw for optimal operation.
All closed-housing tuners are permanently lubricated with Schaller special grease for completely maintenance-free longevity. Designed with identical mounting dimensions to its classic predecessor, the M6 135 installs seamlessly as a direct replacement.
