Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and superior tuning comfort with an advanced 1:18 gear ratio. All components are high-precision CNC-machined and surface-treated to guarantee smooth, delicate, and stable tuning via a self-locking drive system.
Crafted with premium brass string posts precision-fitted into the housing, these closed tuners ensure maximum tuning stability and wear resistance. Every unit is permanently lubricated with Schaller special grease, rendering the mechanism completely maintenance-free.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) diameter base, the post centers reliably via the banjonut without requiring stepped headstock drilling. This design eliminates tilting torque and protects mounting hardware, while retaining identical installation dimensions to previous models for direct replacement.
