Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets a high standard for closed tuning machines, featuring a precise 1:18 gear ratio for smooth, accurate, and comfortable tuning. Every component is CNC-machined to exacting tolerances, complete with a self-locking drive and premium surface finishing that ensures sensitive, stable performance and exceptional tuning stability.
Equipped with high-grade brass posts precisely fitted to the housing, this tuning machine delivers wear-free operation. The stepped M6 collar washer centers the string post securely via the banjo bolt, eliminating the need for a stepped peghead hole while removing tilting torque and taking mechanical pressure off both the post and mounting screw.
Featuring permanently lubricated internal components with Schaller special grease, the M6 135 operates completely maintenance-free. It shares identical mounting dimensions with its predecessor model, allowing seamless retrofitting on compatible solid or slotted guitar headstocks without modifications.
