The 90's Ibanez UV7 used by Trey Azagthoth had the DiMarzio Blaze II pickups. These DiMarzio Blaze II pickups were exclusive to the UV7 and were never released in the market by DiMarzio.

These 90's DiMarzio Blaze II are completely different from the current genertion DiMarzio Blaze DP702 pickups. The current generation Blaze DP702 pickups have a different base plate causing the sound to be more controlled. Their design changes are supposed to make the low end tighter. However in order to achieve so they sacrifice the raw and thick growl that the 90's DiMarzio Blaze II pickups used to have.

What guitars did use on this album?

I used my B.C. Rich Ironburn, Gibson Explorer for the rhythms and six-strings.[sic] I used 2 different Ibanez Universes for the seven-strings. For solos, I used my B.C. Rich Ironburn, my orange Ibanez Stratocaster and a few other guitars, but it was mainly those 2 guitars for soloing.[sic]
