Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an evolution of the iconic original, featuring an improved 1:18 gear ratio for exceptionally precise and smooth tuning. Every component is CNC-machined and finished to tight tolerances, ensuring velvety operation, high tuning stability, and wear-free performance.
Equipped with high-grade brass string posts and permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilt and removing excess pressure from both the post and mounting screws.
Designed as a direct replacement for legacy closed tuners without requiring headstock modifications, this tuning machine delivers unmatched reliability. It installs easily onto modern and vintage headstocks alike, providing professional-grade performance and rock-solid intonation.
