Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed with high-precision CNC-machined components and high-grade brass string posts, it ensures lasting tuning stability and wear-free performance.
Featuring the innovative stepped M6 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 completely maintenance-free functionality.
Equipped with dual rear locating pins spaced 0.39 in (10 mm) center-to-center, the housing directly replaces legacy single-pin M6 models. Premium finishes and precision craftsmanship provide dependable performance for electric and acoustic guitars.
