Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets an advanced standard for closed guitar tuning machines, featuring a precise 1:18 gear ratio for smooth, velvety tuning and exceptional pitch stability. Engineered with high-precision CNC-machined components, each unit delivers self-locking drive performance and reliable wear-free operation.
Crafted with premium brass string posts carefully fitted into the housing, the mechanism maintains optimal string tension and accurate alignment. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moments and avoiding the need for stepped headstock boreholes.
Permanently lubricated with Schaller special grease, these maintenance-free tuning machines are built for straightforward installation and direct replacement on standard headstocks without modification.
