Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 Guitar Tuning Machine offers precision tuning and stability for solid and slotted headstocks. Engineered with an optimized 1:18 gear ratio, this closed-gear tuner delivers smooth, accurate adjustments and velvet-like operation. Every component is CNC-machined to precise tolerances and treated with specialized permanent lubricant for maintenance-free performance.
Featuring high-grade brass string posts fitted directly into the robust housing, the M6 135 ensures maximum wear resistance and tuning retention. The innovative stepped flanged washer centers the string post securely across the hollow screw, eliminating tilt torque and protecting headstock mounting screws without requiring stepped drilling.
Built with identical mounting dimensions to its classic predecessor, the M6 135 enables effortless drop-in replacement on electric and acoustic guitars. Premium build quality, self-locking drive mechanics, and refined finish options make this tuner an industry benchmark for discerning guitarists and luthiers.
