Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin Guitar Tuning Machine represents the modern evolution of an industry-standard closed tuning machine, featuring a high-precision 1:18 gear ratio for smooth, accurate, and stable tuning. Each tuner is equipped with precision CNC-machined components and high-grade brass posts fitted seamlessly into the housing to ensure long-term wear resistance and consistent performance.
An innovative stepped flanged collar centers the string post securely through the banjo bolt, eliminating tilting moment and relieving stress on both the post and rear mounting elements without requiring a stepped peghead bore. Sealed construction with permanent Schaller specialty lubrication guarantees maintenance-free operation across years of play.
Designed with a dual-pin mounting configuration featuring a 0.39-inch (10 mm) pin-to-pin distance, these tuning machines provide a direct retrofitting solution for original single-pin M6 installations while sharing the identical outer housing footprint. Complete sets include mounting screws, threaded bushings, and stepped flanged collars for straightforward guitar installation.
