Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers refined functionality and dependable performance. Engineered with a precise 1:18 gear ratio, it provides smooth, velvety tuning action and superior pitch stability. High-precision CNC machining and high-grade brass string posts ensure wear-free operation and exceptional longevity.
Featuring the stepped M6 collar washer with a 0.39 in diameter base, this tuning machine centers the string post reliably through the hollow screw. This design eliminates tilting torque, relieving pressure from both the post and the rear mounting screw without requiring stepped headstock drilling.
Designed to match the exact mounting dimensions of its predecessor, the M6 135 allows direct replacement and hassle-free installation on solid headstocks. Each sealed housing is permanently lubricated with Schaller special grease for completely maintenance-free performance.
