Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine features a precise 1:18 gear ratio that delivers velvety smooth tuning and exceptional pitch stability. High-precision CNC-machined parts with surface refinement work alongside a self-locking drive to provide consistent, sensitive, and reliable operation across all playing environments.
Equipped with high-grade brass string posts carefully fitted into the housing, this tuning machine guarantees maximum wear resistance. The innovative stepped M6 flanged washer reliably centers the string post through the banjo bolt without requiring a stepped peghead bore, eliminating tilting moments and relieving stress from both the post and mounting screw.
Every sealed tuning machine comes permanently lubricated with specialized Schaller grease for completely maintenance-free performance. Designed to replace original classic M6 units without headstock modification, it includes mounting screws, stepped flanged washers, and banjo bolts for immediate installation.
