Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin series sets a high standard for closed tuning machines, featuring a precise 1:18 gear ratio that ensures velvet-smooth and exact tuning stability. Every individual component is precision CNC-machined, surface-finished, and driven by a self-locking gear mechanism to provide reliable and wear-free performance over time.
Crafted with premium brass string posts and permanently lubricated with Schaller special grease, these tuners deliver long-lasting, maintenance-free operation. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock holes, eliminating tilt torque and protecting structural integrity.
Designed with a dual-pin mounting configuration featuring a 0.39-inch (10 mm) pin spacing and a 0.31-inch (8 mm) spacing from the pin to the center of the post, this tuning machine provides a solid fit for modern guitar headstocks.
