Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 tuning machine features an optimized 1:18 gear ratio that delivers exceptional precision, smooth operation, and effortless tuning stability. CNC-machined components with self-locking drives ensure balanced, precise, and consistent performance for demanding players.
Crafted with premium brass string posts fitted accurately into the housing, this enclosed tuner guarantees minimal wear and maximum durability. The innovative stepped flanged washer centers the string post securely without requiring stepped peghead drilling, eliminating tilting moments and relieving mechanical stress.
Permanently lubricated with specialized Schaller grease for entirely maintenance-free operation, the M6 90 shares identical installation dimensions with its classic predecessor, allowing for direct drop-in replacement without instrument modification.
