Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability with an improved 1:18 gear ratio. Designed with the identical mounting dimensions as its predecessor, it allows direct retrofitting and replacement without modifying the headstock.
Crafted with CNC-machined components and high-grade brass posts fitted into durable housings, these closed tuners feature self-locking drives and permanent lubrication with Schaller special grease for completely maintenance-free performance. The innovative stepped M6 flanged washer ensures precise string post centering without requiring stepped peghead drilling.
Available in versatile configurations including Locking and TopLocking mechanisms, each set includes threaded bushings, flanged washers, and mounting screws for complete installation.
