This comment was a faux paux in the Ibanez catalogue's, the 7620 didn't have dimarzio blaze pickups in it, it has the standard Ibanez 7 pickups in it that the 7420 was supposed to have. there were a couple different versions of each, but a phone call with hoshino told me that the RG7's never came with dimarzio's in them.
Just a little FYI based on what I was told. (which could still be wrong )
The pickups in my 7620 are Dimarzios, The say so on the bottom
