Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined to exact tolerances, high-grade finished, and engineered with a self-locking drive mechanism for stable, delicate, and uniform tuning performance.
Constructed with premium brass string posts precisely fitted into the housing, these tuning machines provide maximum tuning stability and wear-free operation. The specialized stepped M6 washer ensures seamless installation and lasting axis centering through the threaded bushing without requiring stepped peghead drilling.
