Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an optimized 1:18 gear ratio. Continuing the legacy of the original closed tuning machine established in 1966, this model incorporates CNC-machined components and high-grade brass posts to ensure smooth operation and long-lasting tuning stability.
Equipped with an innovative stepped flanged washer, this tuning machine aligns the post reliably without requiring a stepped headstock bore. This structural design eliminates tilting torque and relieves mechanical stress from both the string post and rear mounting screws.
Permanently lubricated with specialized grease, all enclosed housings remain completely maintenance-free. Self-locking drive mechanics provide uniform, sensitive adjustment and exceptional resistance to wear during standard play and aggressive tuning.
