With the original M6 having set the standard for closed-type tuning machines worldwide for half a century the new M6 offers numerous upgrades and improvements without losing its iconic halo.

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.

Additionally the new 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.
