Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability for solid and slotted headstocks. Built with a 1:18 gear ratio, it delivers velvety-smooth operation and sensitive, reliable adjustments. High-precision CNC-machined parts and a self-locking drive ensure lasting performance and wear-free operation.
Crafted with premium brass string posts and factory-lubricated with Schaller special grease, this closed-type tuning machine is completely maintenance-free. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moment and removing pressure from mounting screws without requiring stepped peghead holes.
Featuring the exact installation dimensions of its classic predecessor, the M6 135 allows direct replacement without instrument modification. Each set includes mounting hardware, flanged washers, and banjo bolts for straightforward installation on a variety of headstock configurations.
