Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers precise tuning and outstanding stability. Engineered with an improved 1:18 gear ratio, it ensures smooth and sensitive operation for guitars with solid or slotted headstocks.
Crafted with high-precision CNC machining, each tuner features durable brass posts precisely fitted into the housing, supported by a self-locking drive and permanent lubrication with Schaller special grease for maintenance-free longevity.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the threaded bushing, eliminating tilt moments and relieving pressure from the mounting screws.
