Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a high standard for closed tuning systems, featuring a precise 1:18 gear ratio that provides an exceptionally smooth and accurate tuning experience. CNC-machined components with premium surface finishing and a self-locking drive ensure uniform, stable tuning with maximum wear resistance.
Equipped with high-grade brass posts fitted seamlessly into the housing, this machine delivers optimal tuning stability and tone transfer. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock hole, eliminating tilting torque and protecting the instrument.
Designed to match the mounting dimensions of previous M6 models, it allows for direct replacement without guitar modifications. All internal closed gears are permanently lubricated with Schaller special grease for completely maintenance-free operation.
