Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and smooth operation with its refined 1:18 gear ratio. Continuing the legacy of the original 1966 closed-housing design, this modern iteration incorporates high-precision CNC-machined components and self-locking drive mechanics for outstanding stability and control.
Engineered for enduring performance, every post is crafted from premium brass and seated precisely within the housing to eliminate wear and maintain rock-solid tuning. All enclosed gear units are permanently lubricated with specialized grease, guaranteeing completely maintenance-free reliability over years of use.
Installation is simplified by the innovative stepped flanged washer, which features a 0.39-inch diameter base that accurately centers the string post without requiring a stepped peghead bore. This design eliminates tilting torque and distributes pressure evenly away from both the post and the rear mounting screw.
