Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning accuracy and smooth operation with an advanced 1:18 gear ratio. Designed with high-precision CNC-machined components and premium surface finishing, it incorporates a self-locking drive mechanism that guarantees consistent, reliable tuning stability.
Constructed with durable brass string posts engineered to fit precisely into the housing, this enclosed tuner prevents wear while maximizing service life. Permanently lubricated with Schaller special grease, the entire internal mechanism operates completely maintenance-free across demanding performance environments.
Featuring the innovative stepped M6 collar washer with a 0.39 in (10 mm) base diameter, the tuner centers the string post automatically through the banjo bolt without requiring stepped headstock holes. Sharing identical mounting dimensions with its predecessor, it serves as a seamless, modification-free upgrade or replacement.
