Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers refined tuning precision and exceptional mechanical stability. Engineered with a 1:18 gear ratio, it provides ultra-smooth, responsive adjustments suitable for demanding stage and studio performance.
Precision CNC-machined components and high-grade brass string posts guarantee maximum wear resistance and reliable pitch holding. The enclosed housing features permanent Schaller special grease lubrication for smooth, maintenance-free operation over years of active use.
An innovative stepped flanged washer centers the string post securely through the banjo bolt without requiring stepped headstock drilling. This design eliminates tipping torque and evenly distributes string tension across the assembly for seamless mounting and enhanced durability.
