Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents high precision and refined engineering with its 1:18 gear ratio, delivering smooth and accurate tuning stability. Built with CNC-machined components and surface-finished parts, it utilizes a self-locking drive mechanism to ensure sensitive and steady tuning performance.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine provides maximum wear resistance and pitch stability. The stepped M6 flanged washer centers the string post securely through the hollow screw, preventing tilting torque and eliminating the need for stepped headstock drilling.
Designed to match standard M6 mounting dimensions, it enables straightforward replacement without instrument modifications. Sealed permanently with specialized Schaller lubricant, this closed tuner ensures completely maintenance-free operation across demanding performance environments.
