Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio that provides velvety-smooth action and precise tuning control. Each component is CNC-machined to exacting tolerances and treated with a high-grade surface finish, while self-locking drive mechanics ensure rock-solid stability.
Equipped with an innovative stepped collar washer, the M6 Pin reliably centers the string post via the banjo bolt and eliminates the need for stepped headstock drilling. This smart design distributes pressure evenly and prevents tilting torque on both the string post and rear mounting screws.
Built with premium brass string posts precision-fitted into the housing, all enclosed tuners are permanently lubricated with Schaller special grease for completely maintenance-free operation. The two-pin mounting layout retains identical housing dimensions to legacy single-pin designs for straightforward instrument upgrades.
