Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding tuning precision and smooth operation with an improved 1:18 gear ratio. Engineered with high-precision CNC manufacturing, it features a self-locking drive and premium brass string posts fitted seamlessly into the housing for maximum stability and wear resistance.
Featuring Schaller's innovative stepped collar washer with a 10 mm diameter, this tuning machine reliably centers the string post without requiring a stepped peghead bore. This design eliminates tilting torque and absorbs stress from both the post and the rear mounting screw to ensure long-lasting durability.
Permanently lubricated with Schaller special grease for maintenance-free performance, the M6 135 shares identical installation dimensions with its predecessor model, allowing for direct drop-in replacement without headstock modifications.
