Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers state-of-the-art precision and smooth tuning comfort with an improved 1:18 gear ratio. Continuing the legacy of the original 1966 closed tuner design, this modern iteration integrates advanced CNC manufacturing for tight tolerances and velvety operation.
Crafted with high-grade brass string posts fitted directly into the housing, the mechanism provides exceptional tuning stability, self-locking drive security, and wear-free performance. Each unit is permanently lubricated with Schaller special grease, rendering it completely maintenance-free over years of use.
Featuring the innovative stepped M6 flanged washer, it eliminates headstock tilting moments and automatically centers the string post without requiring stepped drilling. Identical in mounting dimensions to predecessor models, it allows seamless installation and upgrades on standard guitar headstocks.
