Why can't I turn the truss rod on my Martin guitar?

The truss rod on most Martin-branded acoustic guitars is set deeper into the neck than on most other acoustic guitars, and as such you may need a longer wrench/key.


Martin sells their own Two Way Truss Rod Wrench that should allow you to adjust this, which can be purchased here.
