Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents the pinnacle of precision tuning, featuring an advanced 1:18 gear ratio that ensures ultra-smooth adjustment and unmatched tuning stability. Designed as the direct evolution of the legendary original sealed tuner first introduced in 1966, it incorporates state-of-the-art engineering without compromising its classic pedigree.
Every component is CNC-machined to precise tolerances and surface-finished for flawless mechanical operation. Premium brass string posts are meticulously fitted into the housing, while closed-housing permanent lubrication with specialized grease guarantees completely maintenance-free performance and exceptional longevity.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine simplifies installation while securing perfect axis centering via the threaded bushing. This feature eliminates tilt torque and reduces physical strain on both the string post and rear mounting screw, offering a drop-in replacement that matches identical footprint dimensions of predecessor models.
