Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 tuning machine sets a high standard for closed tuning machines, featuring a 1:18 gear ratio that provides precise and smooth tuning control. Each component is CNC-machined with high accuracy and surface-treated to deliver stable, backlash-free operation.
Crafted with premium brass string posts precisely fitted into the housing, this machine head ensures maximum tuning stability and wear-free performance. Closed assemblies are permanently lubricated with Schaller special grease for completely maintenance-free functionality.
The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating the need for a stepped headstock bore. This design eliminates tilting torque and absorbs mechanical pressure from both the post and mounting screw, matching previous model dimensions for straightforward installation.
