Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuning machines, offering an improved 1:18 gear ratio for smooth, precise, and highly stable tuning. Every component is CNC-machined and surface-treated, featuring high-grade brass posts fitted tightly into the housing to ensure maximum wear resistance and tuning stability.
Featuring Schaller's innovative stepped flanged washer, this tuning machine reliably centers the string post through the banjo bolt without requiring a stepped bore hole in the headstock. This structural design effectively eliminates tilting torque while relieving mechanical stress from both the post and the rear mounting area.
Built for durability and zero maintenance, each closed housing is permanently lubricated with proprietary Schaller special grease. The dual-pin configuration provides a secure mount with standard 0.39 in center-to-center pin spacing for reliable, long-lasting performance.
