Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering velvet-smooth operation and unmatched tuning stability. Every individual component is high-precision CNC-machined and surface-finished, featuring a self-locking drive mechanism that ensures sensitive and consistent tuning response.
Crafted with premium brass string posts precisely fitted into the housing, this machine head provides maximum wear resistance and dependable performance. The innovative stepped M6 flanged washer reliably centers the post without requiring stepped headstock drilling, effectively eliminating tilting torque and reducing pressure on mounting screws.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 180 directly replaces legacy M6 tuners without instrument modifications. Its refined, closed housing design continues to set the benchmark for modern professional guitar hardware.
