Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets the standard for closed guitar tuning machines, featuring a precise 1:18 gear ratio that provides velvety smooth operation and exceptional tuning stability. High-precision CNC-machined components and self-locking drive mechanics ensure sensitive, steady, and wear-free performance for both solid and slotted headstock instruments.
Equipped with premium brass string posts carefully fitted into the housing, this machine delivers outstanding durability and pitch retention. The integrated stepped flanged washer centers the string post reliably through the hollow bolt, eliminating tilting friction and removing mechanical stress without requiring stepped peghead holes.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 shares identical mounting dimensions with classic models to offer a seamless drop-in replacement across various configuration options.
