Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets a high standard for closed tuning machines, combining historic prestige with modern engineering. Engineered with an improved 1:18 gear ratio, it delivers unmatched precision, velvet-smooth turning, and exceptional tuning comfort for electric and acoustic guitars.
Every component is precision CNC-machined, surface-finished, and fitted with high-grade brass string posts to ensure wear-free operation and supreme tuning stability. Closed housings are permanently lubricated with Schaller special grease, providing completely maintenance-free performance over the lifespan of the machine.
Featuring the innovative stepped M6 flanged washer, this tuner allows straightforward mounting and reliable post centering without requiring a stepped headstock bore. It maintains identical installation dimensions to its predecessor, allowing direct drop-in replacement without instrument modifications.
