Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers refined performance and precision tuning. Featuring an improved 1:18 gear ratio, it ensures smooth, velvety action alongside exceptional tuning accuracy and rock-solid stability.
All components are CNC-machined to precise tolerances, finished to a high standard, and permanently lubricated with Schaller special grease for entirely maintenance-free operation. High-grade brass string posts are fitted into the housing to guarantee maximum durability and wear-free longevity.
Equipped with an innovative stepped flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock bore. The design completely eliminates tilting torque while maintaining identical installation dimensions to previous M6 iterations for effortless replacement.
