Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and reliable tuning stability with an improved 1:18 gear ratio. Designed with the identical mounting dimensions as its predecessor, it allows for direct replacement without instrument modification. All components are CNC-machined and surface-treated for smooth, consistent adjustment.
Equipped with high-grade brass string posts and permanently lubricated with Schaller special grease, these sealed tuners ensure wear-free and maintenance-free operation. The self-locking drive delivers sensitive and dependable performance across demanding playing conditions.
Featuring the innovative stepped M6 flanged washer, the post centers securely via the banjo bolt without requiring a stepped headstock bore. This design eliminates tilting torque and reduces mechanical strain on both the string post and rear mounting screw.
