Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine offers precision engineering and smooth operation with an improved 1:18 gear ratio. Designed with CNC-machined components and surface finishing, it utilizes a self-locking drive mechanism to deliver delicate, stable, and consistent instrument tuning.
Equipped with high-grade brass posts fitted accurately into the housing, this tuning machine provides wear resistance and tuning stability. The stepped M6 flanged washer centers the string post through the banjo bolt, eliminating tilting moments and relieving mechanical stress without requiring a counterbore in the headstock.
Featuring permanently lubricated internal gearing with Schaller special grease, the enclosed design ensures completely maintenance-free performance. It directly matches standard pin-spacing configurations for hassle-free installation and upgrades on compatible solid headstocks.
