Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuners, featuring an advanced 1:18 gear ratio that delivers exceptional precision, velvety smooth action, and long-lasting tuning stability. Each component is CNC-machined to exacting tolerances, surface-finished, and fitted with a self-locking drive mechanism for effortless, sensitive adjustment.
Equipped with high-grade brass string posts engineered for wear-free performance, the M6 Pin incorporates an innovative stepped flanged washer. The stepped design automatically centers the string post via the banjo bolt, eliminating tilting moment and relieving structural strain from both the post and rear mounting screws without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, this sealed tuner offers robust performance for solid headstocks. Designed with a dual-pin mounting configuration, it ensures dependable alignment and rock-solid instrument stability.
