Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry standard with its refined 1:18 gear ratio, delivering precise, smooth, and dependable tuning. All components are precision CNC-machined and surface-finished, featuring self-locking drive mechanisms for delicate and consistent adjustment.
Equipped with high-grade brass string posts fitted accurately into the housing, these tuners ensure outstanding tuning stability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tilting moment and removing the need for a stepped headstock hole.
Featuring permanent Schaller special grease lubrication, every enclosed machine head operates entirely maintenance-free. Designed with standard installation dimensions identical to its predecessor, it allows seamless replacement and upgrading without instrument modifications.
