Schaller M6 180: a benchmark in guitar tuning machines
Originally introduced in 1966, the Schaller M6 has become one of the German brand's most iconic sealed tuning machines.
The current M6 180 generation retains the spirit of this historic tuning machine while benefiting from a modernized design for improved precision, smooth operation and tuning stability.
This version is available in Chrome finish, in a 3 left + 3 right tuning machine configuration, with large Large Metal buttons.
1:18 ratio: precision and tuning comfort
Schaller M6 180 tuning machines use a 1:18 gear ratio.
This ratio allows fine string tension adjustments and facilitates precise tuning, with smooth, consistent button rotation.
The various components are precision-machined by Schaller, and the sealed mechanism is lubricated with a specific grease for maintenance-free operation.
A design built for stability
Schaller uses shafts made from high-quality brass, precisely fitted into the housing to promote tuning stability and reduce wear.
The M6 180 also benefits from the M6 Step Washer system. Its design properly centers the shaft in the bushing and ensures stable mounting of the tuning machine on the guitar headstock.
-Large Metal buttons
This version features fully metal Schaller Large Metal buttons.
Larger than Small Metal buttons, they offer a comfortable grip while giving M6 tuning machines their classic, robust appearance.
With this button, a complete tuning machine weighs approximately 38 g, including the threaded bushing.
-3+3 configuration
The set includes 3 left-side and 3 right-side tuning machines.
This layout suits guitars with three tuning machines on each side of the headstock, a configuration commonly found on many electric and acoustic guitars.
