Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers state-of-the-art tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed with closed-housing architecture and high-precision CNC-machined components, it provides balanced, sensitive, and stable string tension adjustment.
Featuring high-grade brass string posts precision-fitted to the housing, this machine head offers maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer ensures straightforward installation and durable centering without requiring stepped peghead counterbores, effectively eliminating tilting torque.
Equipped with dual rear mounting pins featuring a 10 mm center-to-center spacing, it fits securely on compatible headstocks. All enclosed housings are permanently lubricated with Schaller special grease for completely maintenance-free performance.
