Schaller M6 90 Guitar Tuning Machine

The Schaller M6 90 tuning machine provides exceptional tuning stability and precision with its refined 1:18 gear ratio. Designed as an evolution of the iconic closed tuner first established in 1966, this model incorporates modern engineering enhancements while maintaining classic aesthetic appeal.
Crafted with CNC-machined components and high-grade brass string posts fitted directly into the housing, each unit ensures smooth, wear-free performance. Permanent internal lubrication using specialized grease keeps the mechanism maintenance-free over extended use.
An innovative stepped flanged washer centers the string post securely via the hollow bolt, eliminating tilting friction and removing the requirement for stepped headstock boreholes. The unit retains identical mounting dimensions to predecessor designs for straightforward installation.
