Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets a high standard for closed guitar tuning machines with an advanced 1:18 gear ratio that delivers exceptional tuning precision and ultra-smooth operation. Every component is CNC-machined and surface-treated to ensure consistent, delicate adjustment and reliable tuning stability through its self-locking drive mechanism.
Crafted with premium brass posts precisely fitted into the housing, the M6 180 prevents wear while maximizing durability. The innovative stepped M6 flanged washer centers the string post securely using a hollow screw, eliminating tilt torque and removing pressure from both the post and the rear mounting screw without requiring stepped headstock holes.
Permanently lubricated with Schaller special grease, these maintenance-free tuning machines are engineered for direct drop-in replacement on existing standard installations. They provide steadfast performance across solid and slotted headstock setups while maintaining the iconic feel and aesthetic integrity of the classic M6 series.
