Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin series sets a high standard for closed tuning machines, featuring a precise 1:18 gear ratio that ensures velvet-smooth, accurate tuning and exceptional pitch stability. High-precision CNC-machined components and self-locking drive mechanisms provide consistent, responsive performance.
Equipped with solid brass string posts precisely fitted into durable housings, these tuning machines offer wear-free operation. The stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock bore, effectively eliminating tilting moments and relieving mechanical stress.
All enclosed machine heads are permanently lubricated with Schaller special grease for completely maintenance-free longevity. Designed with a dual-pin mounting configuration, they offer secure installation and dependable tuning integrity for high-performance guitars.
