The terms “X-bracing,” “forward-shifted bracing,” and “scalloped bracing” are encountered all over the internet and often mentioned by Maury when discussing Martin guitars.

And since Martin simplified their public spec sheets in recent years, there is even less information on their website concerning the details of what bracing is being employed to make their many different models.
