Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed machine heads, offering an upgraded 1:18 gear ratio for smooth, precise, and highly stable tuning. Every component is CNC-machined with high accuracy and surface-finished, featuring self-locking mechanics that ensure long-lasting tuning stability.
Equipped with high-grade brass string posts engineered for wear-free operation, this machine head incorporates an innovative stepped flanged washer with a 0.39 in (10 mm) diameter. This step centers the string post precisely via the banjo bolt, eliminating the need for step-drilled peghead holes and removing mechanical tilting strain.
All enclosed housings are permanently lubricated with Schaller special grease, rendering the unit entirely maintenance-free. Built to original casing specifications with a dual-pin configuration, it ensures dependable mechanical alignment on compatible headstocks.
