Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Designed to build on the legacy of the original closed tuner, it features CNC-machined components and a self-locking drive to provide smooth, stable, and highly accurate adjustments.
Crafted with premium brass string posts fitted directly into the housing, this tuning machine provides maximum wear resistance and pitch stability. The stepped M6 flanged washer centers the string post securely through the banjo bolt, preventing tipping torque and removing unnecessary strain from both the post and mounting screw.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 180 easily replaces previous models without requiring headstock modifications. It offers an ideal upgrade for musicians seeking smooth functionality, reliable clamping options, and enduring German engineering.
