Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin series sets the standard for closed guitar tuning machines with an advanced 1:18 gear ratio that delivers exceptional precision and smooth operation. High-precision CNC-machined components and a self-locking drive ensure sensitive, stable, and wear-free tuning performance.
Crafted with premium brass string posts precision-fitted into the housing, these tuners provide optimal tuning stability and long-term durability. Each unit features a stepped M6 flanged washer with an integrated 0.39 in (10 mm) diameter step, centering the string post without requiring stepped headstock drilling and eliminating tilt torque.
Permanently lubricated with Schaller special grease, all enclosed tuning machines are entirely maintenance-free. The two-pin mounting design ensures secure installation and straightforward alignment on compatible headstocks.
