Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers legendary performance with a precise 1:18 gear ratio for smooth, accurate tuning stability. Each component is CNC-machined and surface-finished, featuring high-grade brass posts fitted into the housing for maximum wear resistance and self-locking drive consistency.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock bore. This specialized design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting area.
All enclosed tuning machines are permanently lubricated with Schaller special grease for completely maintenance-free operation. Engineered with a standard 10 mm pin spacing, these tuners provide exceptional durability and professional-grade tuning precision for premium guitar setups.
