Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering exceptional tuning accuracy and smooth, velvet-like operation. As an evolution of the closed tuner design first introduced in 1966, this model incorporates modern innovations while maintaining high functional reliability.
Every component is CNC-machined to exact tolerances and surface-finished for premium performance. The high-grade brass posts fit into the housing to maximize tuning stability and eliminate wear, supported by a self-locking gear drive and permanent Schaller lubrication that ensures maintenance-free longevity.
Equipped with the stepped M6 flanged washer, this tuning machine enables straightforward installation by centering the string post directly over the banjo bolt. This eliminates the need for stepped headstock drilling while neutralizing tilt moments and relieving mechanical strain on both the string axis and rear mounting screw.
