Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for closed-type tuners, delivering unmatched precision and smooth tuning comfort. Featuring a refined 1:18 gear ratio, every component is CNC-machined and surface-treated to provide a self-locking drive that guarantees even, sensitive, and stable tuning.
Crafted with premium brass string posts fitted precisely into the housing, this machine head ensures maximum tuning stability and wear-free operation. The closed design comes permanently lubricated with Schaller special grease for completely maintenance-free performance over its lifespan.
Installation is streamlined thanks to the innovative stepped M6 flanged washer, which centers the string post securely through the threaded bushing without requiring step-drilling into the headstock. Sharing identical installation dimensions with its predecessor, it offers a seamless replacement and upgrade for solid or slotted headstocks.
