Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine combines precise engineering with legendary tuning performance, featuring an improved 1:18 gear ratio for exceptionally smooth and accurate adjustments. Every component is CNC-machined to exact tolerances, paired with premium brass string posts precision-fitted into the housing to maximize tuning stability and resist mechanical wear.
An innovative stepped M6 flanged washer ensures reliable self-centering of the string post via the banjo bolt, eliminating the need for a stepped peghead bore while removing tilting torque and relieving lateral stress. All enclosed gear mechanisms are permanently lubricated with Schaller special grease to provide entirely maintenance-free, self-locking operation.
Designed for solid headstocks with a dual-pin mounting configuration, this machine maintains identical housing dimensions to predecessor models for straightforward retrofits. The precision-engineered drive ensures sensitive, stable, and slippage-free string tuning across all playing styles.
