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 )
To clear this completely up.
The Ibanez catalog for the first couple of years identified the pickups in the RG7620 as "Blaze 7", the same pickups that are in the Universe. The pickups in the RG are NOT that pickup, they are a similar, but quite different pickup that I've seen referred to as both "New Blaze" and "Blaze II" *I think the consensus is that "New Blaze" is their proper name). They *ARE* DiMarzio sourced and branded OEM pickups, tho. The 74 series guitars (7420 and 7421) both came with Ibanez branded (but I believe DiMarzio designed) V7-7/V7-8 pickups, which are 7-stringe versions of Ibanez's standard pickups. Trust me, if you play them side by side there's NO WAY you couldn't tell hte difference. Mostly because the DiMarzios sound like crap.
