Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers legendary performance with advanced modern engineering. Featuring a refined 1:18 gear ratio, it provides unmatched tuning precision and smooth, responsive adjustments. High-grade brass string posts and CNC-machined components guarantee durable wear resistance and rock-solid pitch stability.
Equipped with an innovative stepped flanged washer, this tuning machine simplifies installation by securely centering the post via the threaded bushing without requiring stepped headstock drilling. This smart design effectively eliminates tipping torque and alleviates pressure on both the string post and rear mounting screws.
Each closed mechanism is permanently lubricated with Schaller special grease for completely maintenance-free operation. Engineered for versatility, the dual-pin configuration matches standard mounting spacing, ensuring consistent alignment and effortless installation on modern electric and acoustic instruments.
