Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets an industry benchmark for closed-type tuners, delivering unmatched tuning accuracy and smooth operation. Engineered with a precise 1:18 gear ratio, it provides refined, velvet-smooth adjustment and exceptional pitch stability. High-grade brass string posts are precision-fitted into the housing to eliminate wear and ensure lasting performance.
Crafted with CNC-machined components and surface-finished parts, each unit features a self-locking drive mechanism for consistent and reliable tuning. An innovative stepped M6 flanged washer centers the string post securely via the threaded bushing, eliminating tilting torque and removing the need for a stepped headstock hole. Permanently lubricated with Schaller special grease, the enclosed mechanism remains completely maintenance-free.
Designed for straightforward installation and direct replacement of earlier versions, the M6 180 offers versatile mounting and configuration options for various headstock types. Each set includes essential mounting screws, flanged washers, and threaded bushings for solid, dependable installation.
