I don't listen to A7X but I'll take a guess that they use 3rds quite a bit to harmonize as well as octaves.

So to harmonize with thirds you go up 3 notes in the scale your using - e minor for example.

Harmonizing can be quite complex. Theres lots of UG lessons on harmonizing that would explain the techniques alot better than I can.

hope that helped
