Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for smooth, high-precision tuning stability. Built with CNC-machined components and premium brass string posts, each tuner delivers sensitive and reliable adjustment for discerning guitarists.
Equipped with Schaller's innovative stepped flanged washer, this design eliminates tilting moments and relieves mechanical stress on both the post and rear mounting screws. It securely centers the string post via the banjo bolt, removing the need for stepped headstock drilling.
Permanently lubricated with specialized Schaller grease for maintenance-free operation, the two-pin housing maintains exact dimensions compatible with previous single-pin configurations with standard 0.4 in pin spacing.
