Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine features a precise 1:18 gear ratio, delivering exceptionally smooth action and dependable tuning stability. Engineered with high-precision CNC-machined components and high-grade brass string posts, it ensures long-lasting, wear-free performance for both solid and slotted headstocks.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine centers the string post accurately without requiring a stepped peghead bore. This advanced design eliminates tilting torque and reduces mechanical strain on both the string post and rear mounting screw.
Featuring permanently lubricated internal gearing with specialized grease, the sealed M6 90 is entirely maintenance-free. It shares identical mounting dimensions with its predecessor, making it an effortless drop-in replacement or upgrade for standard electric and acoustic guitars.
