Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers an advanced 1:18 gear ratio for precise, velvet-smooth tuning and exceptional stability. Precision CNC-machined from premium materials, it features a self-locking drive mechanism that ensures sensitive and consistent performance across all playing conditions.
Equipped with high-grade brass string posts engineered for wear-free durability, this enclosed tuner includes the innovative stepped M6 flanged washer. Designed to fit a 0.39-inch (10 mm) bore, this stepped washer centers the post securely through the banjo bolt, eliminating tilting moments and reducing mechanical stress without requiring headstock modifications.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 135 maintains the identical installation dimensions of its classic predecessor, allowing for seamless drop-in replacement on compatible electric and acoustic guitars.
