Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Continuing the legacy established by the original sealed M6 in 1966, this model incorporates refined CNC manufacturing and premium surface finishing for smooth, responsive, and stable tuning.
Engineered for maximum durability, all string posts are precision-machined from high-grade brass and fitted seamlessly into the housing to ensure wear-free performance. The enclosed design features permanent lubrication with Schaller special grease, making the internal self-locking drive completely maintenance-free.
Installation is simplified through the innovative stepped M6 flanged washer, which centers the string post securely without requiring a counterbore in the headstock. Matching the identical installation dimensions of its predecessor, the M6 135 allows for direct, modification-free retrofitting.
