Schaller M6 Mini Guitar Tuning Machine
The Schaller M6 Mini guitar tuning machine delivers precise tuning and stability in a compact, lightweight housing. Engineered with an upgraded 1:18 gear ratio, it provides smooth, velvety action and accurate fine-tuning, making it ideal for Stratocaster-style headstocks, smaller headstock profiles, and 12-string guitars.
Built with high-grade brass string posts fitted tightly within the enclosure, this closed-gear tuner features self-locking gearing and lifetime internal lubrication with specialized Schaller grease for completely maintenance-free operation. Every component is machined to strict tolerances and surface-finished for long-lasting wear resistance.
Featuring the stepped M6 collar design with a 0.39 in (10 mm) base diameter, the tuner centers the string post reliably through the hollow screw. This innovative construction eliminates tilting torque and alleviates pressure on both the post and the rear mounting screw without requiring stepped headstock drilling.
