Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and stability with its refined 1:18 gear ratio. All components are high-precision CNC-machined and surface-treated to guarantee smooth, sensitive, and reliable operation through a self-locking drive mechanism.
Crafted with premium brass string posts that fit snugly into the housing, this closed tuner provides maximum wear resistance and pitch stability. The innovative stepped M6 flanged washer ensures solid, durable post centering without requiring stepped peghead drilling, eliminating tilting moments and relieving stress from both the post and mounting screw.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 180 serves as a direct, modification-free replacement for previous M6 models on standard solid and slotted headstocks.
