Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, combining legendary heritage with modern precision engineering. Built with high-precision CNC-machined components and high-grade brass string posts, it ensures maximum tuning stability, wear-free performance, and velvet-smooth operation.
Featuring an upgraded 1:18 gear ratio and self-locking drive mechanisms, this tuning machine delivers fine, responsive adjustment and exceptional tuning comfort. Each unit is permanently lubricated with Schaller special grease for completely maintenance-free longevity.
Equipped with an innovative stepped M6 flanged washer with a 0.39 in (10 mm) base diameter, the tuner centers the string post securely through the banjo bolt without requiring a stepped peghead bore, eliminating tilting torque and reducing stress on mounting components.
