Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed as a modernized standard for closed tuners, all parts are CNC-machined to exacting tolerances and surface-finished to ensure consistent, slip-free performance and long-term durability.
Crafted with premium brass posts fitted directly into the housing, this machine head provides maximum tuning stability and wear resistance. Each unit is permanently lubricated with specialized grease for completely maintenance-free operation over its entire lifespan.
Featuring an innovative stepped flanged washer, the M6 180 reliably centers the string post through the banjo bolt without requiring stepped headstock holes. This design eliminates tilting moments and relieves mechanical stress on both the string post and rear mounting screws for a seamless installation.
