Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort thanks to its refined 1:18 gear ratio. Continuing the legacy of the original 1966 closed-gear design, this modernized standard features precision CNC-machined components with a self-locking drive mechanism for stable, sensitive adjustment.
Crafted with premium brass string posts precisely fitted into the housing, the M6 180 guarantees maximum tuning stability, wear resistance, and long-lasting performance. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw, eliminating tilting torque and eliminating the need for a stepped peghead bore.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, these tuners seamlessly fit modern headstocks while offering direct replacement compatibility. Each unit provides exceptional structural integrity and reliable intonation retention under demanding playing conditions.
