Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark in tuning precision and reliability. Engineered with an improved 1:18 gear ratio, it provides velvety smooth action, fine adjustment capabilities, and long-lasting tuning stability. Each component is CNC-machined to exacting tolerances, surface-treated, and permanently lubricated with specialized grease for maintenance-free performance.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine eliminates unwanted play and prevents mechanical wear. The innovative stepped flanged washer centers the string post securely over the banjo bolt, eliminating tipping moments and taking strain off both the post and rear mounting elements without requiring stepped peghead boreholes.
Designed for versatile installation on modern electric and acoustic guitars, the M6 Pin utilizes a two-pin indexing system with an 8 mm center distance to the string post. Whether configured as single tuners or full sets, standard or locking variants, it offers dependable string retention and unmatched tuning accuracy.
