Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry standard with its precise 1:18 gear ratio, offering smooth, exact tuning and unmatched reliability. Each component is CNC-machined and surface-treated, featuring high-grade brass string posts engineered for maximum stability and wear resistance.
Equipped with an innovative stepped M6 flanged washer, this tuning machine reliably centers the string post via the hollow screw and eliminates tilting moment without requiring stepped peghead drilling. All closed tuners are permanently lubricated with Schaller special grease for completely maintenance-free performance.
Featuring the exact installation dimensions of its predecessor model, the M6 135 allows direct replacement and upgrades without headstock modifications.
