Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine sets a high standard for closed tuning machines, featuring an improved 1:18 gear ratio for smooth, precise, and stable tuning comfort. Each component is CNC-machined with high precision, surface-finished, and designed with a self-locking drive to provide consistent and sensitive adjustments.
Equipped with high-grade brass string posts precisely fitted into the housing, these tuners ensure optimal tuning stability and zero wear. The stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tipping torque and relieving pressure from both the post and rear mounting screws without requiring step drilling.
Permanently lubricated with Schaller special grease, all enclosed mechanisms remain completely maintenance-free. Designed with a standard 10 mm (0.4 in) center-to-center two-pin spacing, this model maintains identical housing dimensions to its predecessor for a seamless and secure headstock installation.
