Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 features an optimized 1:18 gear ratio that delivers exceptional tuning precision and velvety-smooth operation. Designed to match the exact mounting dimensions of its iconic predecessor, this enclosed tuning machine enables effortless drop-in replacement without instrument modification.
Precision CNC-machined components and high-grade brass string posts ensure maximum tuning stability and wear-free performance. A self-locking internal drive mechanism combined with permanent Schaller special grease lubrication provides reliable, completely maintenance-free functionality.
The innovative stepped M6 flanged washer centers the string post reliably via the banjo bolt, eliminating tilt torque and protecting headstock mounting screws without requiring stepped drilling.
