Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning stability, featuring a refined 1:18 gear ratio for smooth, accurate adjustments. Originally setting the global standard for closed-type tuning machines in 1966, this updated design incorporates precision CNC-machined components and high-grade brass string posts engineered for wear-free performance.
Equipped with an innovative stepped flanged washer with a 0.39 in (10 mm) base diameter, this tuning machine centers the string post securely through the threaded bushing without requiring stepped headstock drilling. This design eliminates tilting moments and relieves mechanical stress from both the post and the rear mounting screw.
Each unit features a self-locking drive and permanent lubrication with Schaller special grease for completely maintenance-free operation. Engineered for straightforward installation, the M6 180 directly replaces previous-generation models without requiring instrument modifications.
