Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin series sets a high standard for closed tuning machines, featuring an advanced 1:18 gear ratio for smooth, precise, and highly responsive tuning comfort. Each component is CNC-machined with high accuracy and finished to ensure lasting performance and self-locking drive stability.
Equipped with high-grade brass string posts engineered precisely into the housing, these tuners deliver optimal tuning stability and zero wear. The innovative stepped M6 flanged washer centers the post securely through the threaded bushing without requiring a counterbore in the headstock, eliminating tilting torque and reducing strain on mounting points.
Permanently lubricated with Schaller special grease, these maintenance-free tuning machines are built for durability and flawless operation. The two-pin mounting design features a 0.4 in pin-to-pin spacing and an 0.3 in distance from the pins to the post center for seamless integration on compatible guitar headstocks.
