Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering designed to maintain exceptional tuning stability and performance. Featuring a refined 1:18 gear ratio, it provides smooth, sensitive adjustment for precise pitch control. All components are CNC-machined to exacting tolerances and surface-finished to ensure consistent, friction-free operation.
High-grade brass string posts are fitted into the sealed housing to resist long-term wear and eliminate mechanical slack. The sealed enclosure is permanently lubricated with Schaller special grease, delivering reliable, maintenance-free functionality across extended playing sessions. An innovative stepped M6 flanged washer centers the string post precisely through the banjo bolt, preventing tilting moment without requiring stepped peghead drilling.
Designed with standard mounting dimensions identical to its predecessor, this machine installs seamlessly as a direct replacement without requiring headstock modifications. Premium materials and solid construction withstand stringent string tension while delivering dependable durability for demanding musicians.
