Picked up a used Martin 000-15M. Great guitar, but the action is just a little bit high. I called Martin to ask how to lower it. They said to take out the saddle and sand it down. The action will be lowered at the twelfth fret by about two times whatever you sand off. He said no need to mess with the truss rod.

Has anyone here ever done this ? Doesn't sound too difficult, but figured I'd check here before trying it. I initially thought the truss rod would need to be tweaked.

Thanks in advance,,,,,
