Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers legendary performance and unmatched tuning precision with its advanced 1:18 gear ratio. Designed to set the benchmark for closed guitar tuners, every component is CNC-machined to exacting tolerances and treated with a high-grade surface finish for smooth, reliable, and sensitive adjustments.
Equipped with high-grade brass string posts engineered for wear-free durability, this tuning machine features the innovative M6 stepped flanged washer. The 0.39 in (10 mm) diameter washer reliably centers the string post through the banjo bolt without requiring a stepped peghead bore, eliminating tilting torque and minimizing stress on the post and mounting hardware.
Featuring permanent internal lubrication with proprietary Schaller grease, this tuner provides completely maintenance-free operation and exceptional tuning stability. Its precise dual-pin design ensures secure mounting, offering a refined upgrade for electric and acoustic guitars requiring professional-grade hardware.
