Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers exceptional precision and tuning stability, featuring an improved 1:18 gear ratio for smooth, velvety operation. Every component is CNC-machined and surface-treated, utilizing a self-locking drive mechanism to deliver consistent, sensitive adjustment.
Equipped with high-grade brass string posts fitted precisely into the housing, these tuners ensure reliable wear resistance. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilt and removing pressure from both the post and rear mounting screw.
Featuring permanent lubrication with Schaller special grease, these sealed tuning machines are completely maintenance-free. With identical mounting dimensions to its predecessor, the M6 135 serves as a direct drop-in replacement without requiring headstock modifications.
