Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability. Featuring an optimized 1:18 gear ratio, it provides velvety, accurate adjustments to keep your instrument perfectly in pitch. CNC-machined components and high-grade brass posts ensure wear-free, long-lasting performance.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine centers the string post securely without requiring stepped peghead holes. This unique design eliminates tilting moments and relieves tension from both the post and rear mounting screws. It shares identical installation dimensions with its predecessor model for seamless drop-in replacement.
Each closed machine head is permanently lubricated with Schaller special grease for maintenance-free operation. Self-locking drive mechanics prevent slippage during aggressive playing and heavy bending. Premium materials and meticulous manufacturing make it an enduring choice for serious guitarists.
