Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry standard for closed-type tuners, delivering velvety smooth performance and exceptional accuracy. Equipped with an improved 1:18 gear ratio, it offers precise, stable tuning for modern and classic electric and acoustic instruments.
Engineered with high-precision CNC-machined components and wear-free brass string posts, every tuner guarantees long-term durability and tuning stability. Permanently lubricated with Schaller special grease, the sealed design ensures completely maintenance-free operation under heavy playing conditions.
Featuring the innovative stepped M6 flanged washer, the tuning machine centers the string post accurately over the banjo bolt without requiring a stepped headstock bore. Retaining identical footprint dimensions to its predecessor, it allows seamless drop-in replacement and installation.
