Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuning machines, featuring a precise 1:18 gear ratio that ensures ultra-smooth and accurate tuning stability. Every component is CNC-machined to exact tolerances and finished to deliver smooth operation with self-locking precision.
Crafted with premium high-grade brass posts fitted seamlessly into the housing, these tuning machines provide maximum wear resistance and pitch retention. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock drilling, effectively eliminating tilt torque.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 Pin incorporates a standardized 0.39-inch (10 mm) pin spacing and a 0.31-inch (8 mm) spacing between pins and post center for effortless mounting on compatible guitar headstocks.
