Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding tuning precision and smooth operation with an advanced 1:18 gear ratio. All components are CNC-machined to exacting tolerances, featuring high-grade brass string posts engineered for maximum tuning stability and wear resistance.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) base diameter, this design accurately centers the string post through the banjobolt without requiring a stepped peghead bore. This construction eliminates tilting torque and absorbs mechanical strain across both the string post and rear mounting screws.
Equipped with permanent internal lubrication via specialized Schaller grease, these sealed tuners operate completely maintenance-free. Self-locking drive mechanics ensure highly sensitive, uniform, and stable performance across standard, locking, and staggered headstock configurations.
