Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an advanced 1:18 gear ratio. Designed as an evolution of the iconic original closed tuner from 1966, this model features high-precision CNC-machined components and high-grade brass string posts engineered for maximum tuning stability and wear resistance.
An innovative stepped M6 flanged washer ensures straightforward installation and lasting center alignment of the string post via the banjo bolt, eliminating the need for a stepped headstock hole. This design absorbs lateral pressure from both the post and the rear mounting screw to ensure reliable, long-term performance.
Each closed tuner is permanently lubricated with Schaller special grease for completely maintenance-free functionality. The self-locking drive mechanism provides sensitive, uniform adjustments, while the slightly refined housing dimensions allow for direct retrofit replacement on standard configurations without instrument modifications.
