Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets a benchmark for closed-type tuning mechanisms, featuring a refined 1:18 gear ratio that ensures velvet-smooth tuning and pinpoint precision. Precision CNC-machined components and premium surface treatments combine with high-grade brass string posts to deliver flawless tuning stability and complete wear resistance.
Equipped with the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the threaded bushing without requiring stepped headstock holes. This design prevents tilting moments and relieves mechanical strain from both the post and the rear mounting screw.
Engineered for permanent reliability, every unit is permanently lubricated with Schaller special grease for maintenance-free operation. Its direct replacement design ensures easy mounting on standard headstocks while upholding classic look and function.
