Since the launch of the open back GrandTune™ tuning machine series in 2014 Schaller’s 18:1 Velvet-Tec™ technology has found its way onto most of the finest headstocks of Schaller industry.
Introducing the actual M6 and M6 Mini tuning machine series – featuring 18:1 Velvet-Tec™ and LX6-Lube™ for unparalleled tuning precision and comfort.  
The actual M6 shares the identical footprint with its predecessor and can easily be swapped with no modifications necessary.
M6 step-washer will allow for trouble-free installation and perfectly and permanently centered stringposts. A true Schaller innovation that improves installation and provides added protection to your M6’s longevity and flawless operation. The M6 step-washer instantly centers your stringpost and makes the drilling of two separate diameter holes into your headstock obsolete. The added support eliminates tilting and releases stress from the stringpost and the mounting screw in the back.
