Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for closed-type tuners, delivering unmatched tuning comfort and stability. Engineered with a refined 1:18 gear ratio, it ensures velvet-smooth, highly precise, and reliable tuning performance across all applications.
Crafted with precision CNC-machined components and surface finishes, all internal string posts are constructed from premium brass to eliminate wear and maintain peak tuning stability. The enclosed mechanism comes permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring the innovative stepped M6 flanged collar with a 0.39 in (10 mm) base, this design eliminates the need for stepped headstock drill holes while centering the string post securely. It effectively absorbs lateral pressure and tilting moments, protecting both the string post and rear mounting screw for enduring durability.
