Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin represents the evolution of a legendary tuning machine, offering an upgraded 1:18 gear ratio for velvet-smooth tuning and pinpoint accuracy. High-precision CNC machining and self-locking drive mechanics ensure stable, responsive string tension across every turn.
Crafted with premium brass posts and housed in a permanently lubricated enclosed design, each unit guarantees zero-maintenance operation and unmatched wear resistance. The specialized stepped M6 washer perfectly centers the string post without requiring a stepped headstock bore, eliminating tilt torque and protecting hardware from stress.
Featuring dual mounting pins spaced at 0.39 in (10 mm), these tuning machines deliver secure alignment and rock-solid tuning stability for premium guitar configurations.
