Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and comfort with an enhanced 1:18 gear ratio. CNC-machined components and high-grade brass string posts ensure velvet-smooth operation, high tuning stability, and wear-free performance across all playing conditions.
Featuring an innovative stepped flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock bore. The sealed housing comes permanently lubricated with Schaller special grease for entirely maintenance-free longevity.
Engineered with a standard 0.39-inch (10 mm) center-to-center pin spacing and a 0.31-inch (8 mm) spacing from the pin line to the post center, the dual-pin design securely fits matching headstocks while eliminating rotational play and mechanical strain.
