Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, featuring an advanced 1:18 gear ratio that provides velvety smooth operation and pinpoint tuning precision. Each component is CNC-machined to exact tolerances, paired with premium brass string posts engineered for maximum tuning stability and wear-free longevity.
An innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tipping moments and taking mechanical load off both the string post and rear mounting screws without requiring stepped peghead drilling. All closed-housing tuners are permanently lubricated with proprietary Schaller grease for entirely maintenance-free performance.
Designed with a precise two-pin mounting layout featuring a 0.39 in center-to-center pin spacing and an 0.31 in distance from pins to string post center, this tuner delivers effortless replacement and rock-solid alignment on compatible headstocks.
