Schaller M6L Locking Tuners - Pin Fit, Set of 3 by 3 Machine Heads

The Schaller M6L comes with a locking mechanism to lock the string in place rather than winding around the post. The string is threaded as usual through the eye of post and then, using the thumbwheel on the back of the tuner body, the pin is tightened against the string. You would then tune the guitar up as usual. Changing strings is quick and easy!

The locking mechanism also improves your guitar's tuning stability. Guitar strings tend to slip when wound around the post, often after aggressive playing or bending - having a locking mechanism completely removes this problem.

These Schaller M6L Locking Tuners are mounting via 2 pins on the underside of the tuner body.

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.
