Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and dependable tuning stability for guitars. Featuring an advanced 1:18 gear ratio, it ensures precise, smooth, and sensitive adjustment during performance and practice.
Crafted with premium brass string posts and CNC-machined components, the enclosed housing is permanently lubricated with Schaller special grease for completely maintenance-free operation. The self-locking drive mechanism delivers consistent feel and long-term durability without mechanical wear.
An innovative stepped M6 flanged washer centers the string post reliably through the banjonut, eliminating the need for a stepped peghead bore and protecting both the post and mounting screws from tilt torque.
