Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a high standard for closed tuning mechanisms, combining classic heritage with refined engineering. Featuring an advanced 1:18 gear ratio, it ensures precise, smooth, and sensitive tuning with outstanding stability across all playing conditions.
Crafted with precision CNC machining and premium brass string posts, every component is engineered for durable, wear-free performance. The self-locking drive and internal permanent lubrication with Schaller special grease provide maintenance-free operation and exceptional durability.
Installation is streamlined thanks to the innovative stepped M6 flanged washer, which centers the string post perfectly over the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting moments and reduces mechanical stress on both the post and rear mounting pins.
