To the OP, if you want "passive" tone, why are you asking about actives?

If you want passive tone, get passives, because actives sound nothing like passive pickups.
People have said it on this forum before, that Blackouts sound more "passive" than EMGs, but as an owner of Blackouts, I don't buy it at all.
If anything, the Blackouts sound even more hi fi and have even more of the qualities people associate with actives.
Does this make active pickups a bad thing?
Hell no.
Just embrace actives for what they are. They do many things far superior to passives, and for modern metal, you just cannot beat actives.
