Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, delivering unmatched tuning accuracy and smooth operation. Featuring a precision 1:18 gear ratio and self-locking drive mechanism, it ensures sensitive, stable adjustments that keep your instrument perfectly in pitch.
Constructed with high-grade CNC-machined components and wear-free brass string posts, every tuner is permanently lubricated with Schaller special grease for maintenance-free longevity. The innovative stepped M6 flanged washer reliably centers the string post without requiring stepped headstock drilling, eliminating tilt torque and relieving stress on mounting screws.
Designed to match the original installation dimensions of its classic predecessor, the M6 135 allows direct drop-in replacement without instrument modifications. It combines legendary heritage with modern mechanical enhancements to provide maximum tuning stability for discerning players.
