Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin series sets a high standard for closed guitar tuning machines, featuring a precise 1:18 gear ratio that provides velvety-smooth operation and superior tuning stability. Every component is CNC-machined and finished with precision, while self-locking drive mechanics ensure consistent, delicate, and reliable tuning across all strings.
Crafted with premium brass string posts that fit into the housing, these tuners deliver maximum wear resistance. The innovative stepped M6 flanged washer with a 0.39-inch diameter reliably centers the string post through the banjo bolt, eliminating tilt torque and protecting against excessive pressure without requiring a stepped peghead bore.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 Pin incorporates a two-pin rear mounting configuration with a 0.39-inch pin distance. The set includes complete installation hardware with banjo bolts, flanged washers, and M2.2 x 0.37-inch mounting screws.
