The new M6 is the legend perfected
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 of our industry.
Introducing the all new M6 and M6 Mini tuning machine series – featuring 18:1 Velvet-Tec™ and LX6-Lube™ for unparalleled tuning precision and comfort.
1.) The new M6 shares the identical footprint with its predecessor and can easily be swapped with no modifications necessary.
2.) For the Locking version, please select the corresponding locking post. In the picture you can see the difference.
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.
Please unscrew the black TopLocking screw as far as it will go and then pull it off. Install the machine head on the headstock and then press the TopLocking screw onto the post and screw it tight.
