Schaller M6 90 Guitar Tuning Machine

The Schaller M6 90 guitar tuning machine represents the benchmark in closed tuning machine technology, featuring an advanced 1:18 gear ratio for velvety smooth and precise tuning accuracy. All precision parts are CNC-machined and surface-treated to deliver a self-locking drive mechanism that guarantees lasting tuning stability and sensitive adjustment.
Constructed with high-grade brass string posts fitted precisely into the housing, these tuners offer superior wear resistance and durability. The innovative stepped M6 flanged washer ensures straightforward installation and dependable axis centering directly through the banjo bolt, eliminating the need for stepped peghead holes and preventing lateral tilting torque.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 90 retains identical mounting dimensions to its classic predecessor, allowing for seamless replacement and upgrades without headstock modifications.
