Yeah, they are the New7's/Custom7's... same pups that are in the 1077 and 7620.
They're actually pretty decent sounding for Ibanez stock pickups, but I changed 'em in my 1077 to
Dimarzio Blaze neck/single/custom, which brought just a little more definition to my tone (the Blazes are some of my favorite pickups of all time).
You should have no problems tuning it to B... that's how mine was tuned when I received it, and I played it that way for several weeks before I retuned it to AEADGBE. The extra length is most noticable when riffing down by the nut, but it didn't take long to get used to.
