Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets a high standard for closed tuning machines, offering exceptional precision and smooth operation with an improved 1:18 gear ratio. All components are CNC-machined with high accuracy, surface-treated, and driven by a self-locking mechanism for consistent, responsive tuning.
Featuring premium brass string posts that fit snugly into the housing, these tuners ensure outstanding tuning stability and wear-free performance. The specialized stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing pressure on mounting screws.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 135 matches the exact installation dimensions of its predecessor for seamless drop-in replacement on electric and acoustic guitars.
