Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin series sets the standard for closed guitar tuning machines with an improved 1:18 gear ratio for precise, velvet-smooth tuning and long-lasting pitch stability. Every component is CNC-machined with high precision and surface-treated, featuring a self-locking drive and premium brass string posts carefully fitted to the housing.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the banjo bolt, eliminating tilt and unnecessary strain on mounting hardware without requiring stepped headstock drilling.
Each unit is permanently lubricated with proprietary Schaller special grease for completely maintenance-free operation and exceptional durability.
