Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a high standard for closed tuning systems, combining classic engineering with refined modern enhancements. Featuring an improved 1:18 gear ratio, it delivers unmatched precision, sensitive adjustment, and exceptionally smooth tuning operation.
Precision CNC-machined components and premium brass string posts ensure wear-free longevity, optimal tuning stability, and reliable self-locking performance. All enclosed tuners are permanently lubricated with Schaller special grease for completely maintenance-free operation over their lifespan.
Equipped with an innovative stepped M6 flanged collar, this tuning machine reliably centers the string post via the banjo bolt and eliminates tilting torque without requiring a stepped peghead bore. It is designed with dual rear locating pins spaced 0.39 in (10 mm) center-to-center for secure, screwless rear anchoring.
