Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine combines legendary design with modern engineering. Featuring a refined 1:18 gear ratio, it delivers velvety-smooth action, fine control, and outstanding tuning stability for discerning musicians.
Precision CNC-machined components and high-grade brass string posts ensure wear-free performance and flawless string alignment. Each closed tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation over its lifespan.
An innovative stepped M6 flanged washer centers the string post reliably through the banjobolt without requiring stepped peghead bore holes. This design eliminates tilting torque and protects both the post and mounting hardware against unwanted stress.
