Schaller M6 90 Guitar Tuning Machine

The Schaller M6 90 guitar tuning machine delivers high-precision tuning stability with an advanced 1:18 gear ratio for smooth and accurate adjustments. Engineered from CNC-machined components with high-grade brass posts, it guarantees durability, smooth operation, and wear-free performance.
Equipped with Schaller's innovative stepped flanged washer, this machine head centers the string post securely without requiring stepped peghead holes. This smart design eliminates tilting moments and relieves mechanical pressure from both the post and the rear mounting screw.
Featuring permanently lubricated closed gearing with special Schaller grease, the M6 90 offers completely maintenance-free operation. It matches standard vintage M6 mounting dimensions, allowing effortless direct-replacement installation on compatible guitar headstocks.
