Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry standard with its refined 1:18 gear ratio, delivering precise, velvety-smooth tuning and dependable pitch stability. Engineered with precision CNC-machined components and premium brass string posts, it ensures long-lasting, wear-free performance across all playing styles.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post via the banjo bolt, eliminating tilt torque and protecting against excessive lateral pressure. The self-locking drive and enclosed housing come permanently lubricated with Schaller special grease for entirely maintenance-free operation.
Designed with standard 0.39-inch (10 mm) pin spacing and a 0.31-inch (8 mm) center-to-pin distance, this tuner offers seamless installation and rock-solid mounting. The durable construction and high-grade finishes provide superior mechanical performance and elegant aesthetic appeal for precision instrument upgrades.
