Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for precise and smooth tuning performance. Precision CNC-machined components with self-locking drive mechanisms provide sensitive adjustments and exceptional tuning stability.
Crafted with premium brass string posts and permanently lubricated with Schaller special grease, these maintenance-free tuning machines are built for wear-free durability. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilt and removing stress from mounting screws without requiring stepped headstock holes.
Designed to fit modern and vintage instruments, the M6 180 directly replaces previous iterations without modifications. Each set includes hollow banjo bolts, stepped flanged washers, and mounting screws for straightforward installation on solid and slotted headstocks.
