Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. All components are high-precision CNC-machined and surface-treated to guarantee smooth, sensitive, and stable operation through a self-locking drive mechanism.
Crafted with premium brass string posts precision-fitted into the housing, this machine head offers maximum tuning stability and wear resistance. An innovative stepped M6 flanged washer ensures straightforward installation and durable post centering without requiring a stepped headstock bore.
Featuring permanent lubrication with Schaller special grease, the closed housing is completely maintenance-free. It shares identical mounting dimensions with its predecessor model, allowing seamless replacement and upgrades without instrument modifications.
