Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a high standard for closed tuning machines, featuring a precise 1:18 gear ratio for smooth, accurate, and stable tuning comfort. CNC-machined parts and high-grade brass posts ensure seamless operation, maximum wear resistance, and reliable performance.
Equipped with Schaller's innovative stepped flanged washer, this tuner guarantees effortless installation and permanent self-centering of the string post via the banjo bolt. This specialized design eliminates tilting torque and reduces mechanical stress on both the post and fixing hardware without requiring stepped peghead counterbores.
Permanently lubricated with Schaller special grease, each enclosed unit is entirely maintenance-free. Designed with a dual-pin mounting configuration spaced 10 mm (0.39 in) center-to-center and an 8 mm (0.31 in) pin-to-post offset, it delivers rock-solid stability and modern engineering precision.
