Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin sets a refined benchmark for enclosed tuning machines, featuring a precise 1:18 gear ratio for exceptionally smooth and accurate guitar tuning. Every component is CNC-machined with high precision and surface-finished to ensure uniform, sensitive, and stable tuning performance with a self-locking drive mechanism.
Crafted with premium brass string posts precisely fitted into the housing, these tuners deliver unmatched tuning stability and wear-free operation. The permanently lubricated internal mechanism utilizes Schaller special grease, rendering the unit completely maintenance-free over its entire lifespan.
An innovative stepped M6 flanged collar with a 0.39-inch diameter base enables effortless mounting and ensures permanent centering of the string post via the banjo bolt. This engineering feature eliminates tilting torque and relieves mechanical stress from both the post and mounting screws.
