Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents high-precision engineering with an advanced 1:18 gear ratio, delivering ultra-precise tuning feel and exceptional pitch stability. Built on the iconic legacy of the original 1966 closed-housing design, this modernized unit incorporates refined internal mechanics and CNC-machined components for velvety, backlash-free operation.
Crafted with premium high-grade brass string posts fitted directly into the robust housing, each tuner ensures long-term wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating the need for a stepped peghead bore while removing lateral tilt torque and reducing stress on the rear mounting screw.
Each enclosed tuner is permanently lubricated with proprietary Schaller grease for lifelong, maintenance-free performance. Designed as a direct, modification-free replacement for previous iterations, it delivers supreme stability and professional-grade reliability for demanding instruments.
