Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets the standard for closed tuning machines with high precision and tuning comfort. Engineered with a refined 1:18 gear ratio, it ensures an ultra-smooth, velvet-like tuning experience and exceptional pitch stability. Every component is CNC-machined to exacting tolerances and self-locking for consistent performance.
Crafted with premium high-grade brass string posts fitted directly into the durable housing, this tuner maximizes wear resistance. The innovative stepped M6 flanged washer centers the post reliably via the banjonut, eliminating tilting torque, protecting mounting components, and removing the need for a stepped peghead bore.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 Pin utilizes a dual-pin mounting design with a 0.4 in (10 mm) pin-to-pin spacing. Built with uncompromising German engineering, it provides secure string clamping and enduring reliability for demanding musicians.
