Al Di Meola – All Your Life: A Tribute to the Beatles

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.

About an hour in the video you can see a Guild 12 string acoustic, said to be used in the beatles tributes album

"Last night I rediscovered my very first Les Paul which was basically buried behind a wall of other guitars that I hadn’t actually touched in more than 30 years. I bought it when I was 17 years old, I ordered it from the famous Manny’s Music on 48th street. It was used on the first three RTF albums, Land of the Midnight Sun and exclusively as well on Elegant Gypsy. I completely forgot how this guitar sounds! Now I’m going to use it on my new studio album, Beatles tribute II. Then I recalled in the day when I was using this guitar that I was adamant against using any effects and I was one of the purists that preferred going direct. Then it dawned on me that somewhere deep in my warehouse of stuff may be two or three 50w Marshalls from the 70s which made that sound an iconic sound of the time. Luckily, after tearing through a ton of stuff, I was blown away to find that one of the Marshalls in particular sounded as good as it did in the heyday. I think there is no more powerful combination. What an epiphany!" (June 2,2019) - Al Di Meola
