After some searching of what kinds of guitars Al DiMeola used in his arsenal, I stumbled across this picture of what looked like Al playing a Martin. After some looking into this it turned out to be a Sigma that he used for recording on his Beatles Tribute album All Your Life. Though it's listed in Spanish, it says the same thing in the link.

The link mentions that the guitar is a SDR-28H Limited Edition which is the SDR-28MLE.
