Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuners with its refined 1:18 gear ratio, delivering smooth and precise tuning accuracy. All components are CNC-machined and finished to exact tolerances, pairing with a self-locking drive for lasting stability.
Solid brass string posts and housing fitments provide exceptional durability and eliminate string slippage under tension. The innovative stepped M6 flanged washer centers the string post reliably through the banjo bolt, removing the need for a stepped headstock bore and preventing tilt torque on mounting screws.
Permanently lubricated with Schaller special grease, each tuning machine offers maintenance-free performance. Designed with a standard 10 mm pin-to-pin spacing and an 8 mm center distance, it ensures dependable installation across solid headstock configurations.
