Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin series sets a high standard for enclosed guitar tuning machines, featuring a precise 1:18 gear ratio that ensures velvet-smooth and exceptionally accurate tuning stability. Every individual component is CNC-machined with high precision and surface-finished, utilizing high-grade brass string posts engineered for maximum durability and wear-free performance.
Equipped with an innovative stepped M6 flanged washer with a 0.39 in diameter, this tuning machine reliably centers the string post via the banjo bolt, eliminating the need for a stepped peghead bore. This design removes tilting torque and significantly relieves mechanical strain from both the post and rear mounting screws.
All enclosed housings are permanently lubricated with proprietary Schaller grease for completely maintenance-free operation. Featuring a dual-pin mounting configuration with a 0.39 in center-to-center pin spacing and an 0.31 in post-to-pin distance, the M6 Pin delivers flawless retrofit integration and lasting performance.
