Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry standard with its enhanced 1:18 gear ratio, offering precise tuning feel and exceptional stability. All components are CNC-machined and finished to deliver smooth, sensitive, and reliable adjustments through a self-locking drive mechanism.
Equipped with high-grade brass string posts fitted accurately into the housing, this enclosed machine head ensures wear-free longevity and peak tuning stability. The stepped M6 flanged washer reliably centers the string post via the hollow screw, removing tilt torque and eliminating the need for stepped headstock drilling.
Featuring permanently lubricated internal gearing with Schaller special grease, this tuner provides completely maintenance-free performance. Designed with identical installation dimensions to its predecessor, it serves as a seamless replacement upgrade for solid or slotted headstock instruments.
