Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuners, combining legendary heritage with refined modern engineering. Featuring a precise 1:18 gear ratio, it delivers velvety-smooth tuning action and exceptional accuracy.
Every component is CNC-machined to exacting tolerances, complete with wear-free brass string posts accurately fitted into the housing for maximum tuning stability. The self-locking drive and permanent lubrication with Schaller special grease ensure consistent, maintenance-free performance.
Equipped with an innovative stepped flanged washer, this tuner allows smooth installation and solid post centering without requiring a stepped peghead bore. This design effectively eliminates tilting torque while relieving mechanical strain on the string post and rear mounting screws.
