Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets a high standard for closed tuning machines, featuring a precise 1:18 gear ratio that delivers velvet-smooth tuning comfort and rock-solid stability. CNC-machined components with premium surface finishing and a self-locking drive ensure consistently sensitive adjustment without backlash.
Equipped with high-grade brass string posts engineered directly into the housing, the M6 135 guarantees wear-free performance and superior tuning retention. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing, eliminating tilting torque and protecting the headstock without demanding stepped reaming.
Permanently lubricated with Schaller special grease for maintenance-free operation, this model shares the exact mounting dimensions of its classic predecessor for direct drop-in replacement. Each set includes mounting hardware, flanged washers, and threaded bushings designed for effortless installation.
