Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning action with an advanced 1:18 gear ratio. Engineered with CNC-machined components and self-locking drive technology, it ensures sensitive and reliable tuning stability.
High-grade brass posts are precision-fitted into the sealed housing, permanently lubricated with specialized grease for completely maintenance-free operation over years of play.
Featuring the innovative stepped flanged washer, the M6 135 reliably centers the string post without requiring stepped headstock drilling, eliminating tilting torque while sharing identical installation dimensions with its predecessor.
