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 and accurate tuning comfort. Every component is CNC-machined and finished to deliver smooth, sensitive, and stable performance with a self-locking drive mechanism.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine delivers high tuning stability and wear resistance. The innovative stepped M6 flanged washer eliminates the need for a stepped peghead bore, centering the string post via the banjo bolt and absorbing mechanical pressure.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 Pin utilizes a dual-pin configuration with a 0.39 in (10 mm) pin spacing designed for standard pin-mount installations.
