Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for closed tuning mechanisms, combining classic heritage with refined modern engineering. Featuring an improved 1:18 gear ratio, it ensures exceptionally precise, smooth, and stable tuning comfort across all playing conditions.
Precision CNC-machined components and high-grade brass string posts provide wear-free longevity and robust tuning stability. Permanently lubricated with Schaller special grease, the sealed housing delivers completely maintenance-free performance and consistent torque.
Equipped with the innovative stepped M6 flanged washer, this tuner centers the string post securely without requiring stepped peghead drilling. It matches the exact installation footprint of previous M6 models for seamless drop-in replacement on compatible guitars.
