Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a high standard for closed tuning systems, combining classic design with modern engineering. Engineered with a 1:18 gear ratio, it delivers velvety-smooth feel and precise tuning stability for solid headstock instruments.
Each component is CNC-machined to precise tolerances, featuring brass posts carefully fitted into the housing and permanently lubricated with proprietary grease for maintenance-free performance. The self-locking drive design ensures an even, responsive, and secure tuning process without slippage.
Equipped with Schaller's stepped flanged washer, this tuning machine simplifies installation by reliably centering the string post through the banjo bolt without requiring stepped headstock drilling. This innovative design eliminates tilting moments and relieves mechanical stress from both the post and mounting hardware.
