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. Each component is CNC-machined to precise tolerances and surface-finished, featuring a self-locking drive mechanism that guarantees even, sensitive, and reliable tuning stability. The brass string posts are precision-fitted into the housing to ensure wear-free performance under continuous string tension.
Equipped with the innovative Schaller stepped flanged washer, this tuning machine simplifies installation while providing robust post centering via the hollow screw. The stepped design eliminates the need for a stepped peghead counterbore, absorbing lateral tilting moments and protecting both the string post and rear mounting screws from undue strain. Factory-lubricated with Schaller special grease, the enclosed housing remains completely maintenance-free throughout its service life.
Featuring two locating pins with a 10 mm center-to-center spacing and an 8 mm distance to the post center, the M6 Pin offers a direct retrofit for corresponding guitar pegheads. High-grade brass and solid componentry provide excellent resonance transfer, making this tuning machine a reliable choice for professional players and luthiers seeking premium guitar hardware.
