Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents the pinnacle of closed tuning technology, featuring a precise 1:18 gear ratio for exceptionally smooth and accurate tuning stability. Built with CNC-machined components and high-grade brass string posts, each tuner ensures flawless mechanical operation and exceptional wear resistance.
Equipped with Schaller's innovative stepped flanged washer, the unit automatically centers the string post via the banjo bolt, eliminating the need for a stepped headstock hole while distributing mechanical tension evenly across the assembly. Permanent lubrication with specialized grease guarantees long-lasting, maintenance-free performance.
Designed to match identical mounting dimensions of original M6 models, this tuning machine allows direct replacement without instrument modification. The precision self-locking drive maintains rock-solid pitch stability under demanding playing conditions.
