The Schaller M6 135C 3x3 Tuning Machines in Chrome.
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.
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.
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 added support eliminates tilting and releases stress from the stringpost and the mounting screw in the back.
Top shelf tuners to complete my project guitar. Precision tuning and AMS had the best price I could find.

Awesome tuners
These are the first set that I have bought. They were easy to install on my Les Paul and they have smooth action and hold tuning amazing well. I would buy more for these for more of my guitars.
