Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and tuning comfort with an improved 1:18 gear ratio. Designed with CNC-machined parts and high-grade brass string posts, it ensures smooth, highly sensitive, and wear-free performance for exceptional tuning stability.
Featuring the innovative stepped M6 flanged washer, this tuner allows effortless installation and solid axle centering without requiring a stepped headstock borehole. This design eliminates tilting torque and reduces mechanical stress on both the string post and rear mounting screws.
Each sealed tuner is permanently lubricated with specialized Schaller grease for maintenance-free operation and matches the exact mounting dimensions of its predecessor for drop-in replacement.
