Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision and tuning comfort with an upgraded 1:18 gear ratio. All components are CNC-machined and finished to deliver smooth, sensitive, and reliable operation with self-locking drive technology.
Equipped with high-grade brass string posts engineered into the housing, these tuners ensure maximum stability and wear-free performance. The specialized stepped M6 flanged washer centers the post reliably through the banion bolt, eliminating tilt and removing stress from the post and rear mounting screw.
Designed with the exact mounting dimensions of its predecessor, the M6 135 allows direct replacement without instrument modification. Each closed-housing tuner is permanently lubricated with Schaller special grease for completely maintenance-free functionality.
