Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers outstanding tuning comfort and refined engineering. Featuring an advanced 1:18 gear ratio, it provides velvety smooth and exceptionally precise tuning action. Every component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Equipped with high-grade brass string posts precisely fitted into the housing, these tuners ensure maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post reliably through the banjo bolt, eliminating tilting moments and removing pressure from both the post and the rear mounting screw without requiring stepped peghead drilling.
Engineered with identical installation dimensions to its classic predecessor, the M6 90 allows for direct, modification-free replacement on compatible headstocks. These tuners combine self-locking drive precision with robust craftsmanship to meet the rigorous performance demands of discerning guitarists.
