Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, delivering unmatched tuning accuracy and smooth performance. Featuring an advanced 1:18 gear ratio, it ensures precise, velvet-smooth adjustments and exceptional tuning stability. All components are CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Crafted with premium brass string posts fitted precisely into the housing, the M6 135 eliminates play and wear over extended use. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw, preventing tilting torque and stress without requiring stepped headstock drilling.
