Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry benchmark for enclosed tuners, offering smooth operation and exceptional tuning stability. Engineered with a 1:18 gear ratio, it delivers precise micro-adjustments for both stage and studio instruments.
Crafted with premium CNC-machined components and solid brass posts, each tuner fits securely into the housing to minimize mechanical play and resist long-term wear. Permanently lubricated with Schaller special grease, the self-locking drive mechanism operates completely maintenance-free.
Featuring the innovative stepped M6 flanged collar with a 0.39 in diameter, the unit centers the post directly over the banjo bolt to eliminate tipping stress without requiring custom stepped peghead reaming. It retains the classic mounting dimensions of original models for direct, hassle-free installation.
