Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets a high standard for closed tuning machines, featuring a precise 1:18 gear ratio that provides velvety-smooth action and exceptional tuning accuracy. Every component is CNC-machined with high precision and surface-finished, utilizing a self-locking drive mechanism to guarantee uniform and stable tuning across all playing conditions.
Crafted with premium brass string posts precision-fitted directly into the housing, these tuners deliver maximum tuning stability and wear-free performance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tilt torque and protecting against stress without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 maintains the identical installation dimensions of previous models for seamless drop-in replacement without instrument modification.
