The Schaller M6 90 guitar tuning machine represents high-precision engineering with an advanced 1:18 gear ratio, delivering exceptionally smooth, fine, and stable tuning comfort. CNC-machined components and premium brass string posts guarantee maximum tuning stability and long-lasting wear resistance.
Equipped with an innovative stepped flanged washer, this tuning machine provides effortless installation and precise centering of the string post via the banjo bolt, effectively eliminating tilting moments and relieving stress from mounting screws without requiring stepped peghead drilling.
