My Loomis blackouts are my fave active pickups ever. I still keep a guitar with an emg 81 in it, but though, because nothing does quite what it does when I want that sound, but the Loomises are phenomenal. Nothing like the basic blackouts, which are way too woofy, loose, and hot. The looms are very tight, with a "just crispy enough" treble to be articulate without stabbing my ear drums, and still hot, just not ridiculously so.
I'm not sure what passives are quite like them. I guess my Pegasus/Sentient combo isn't terribly far away, but they have much less output and a bit less "sproinginess" (sorry, can't think of a better word). Not quite as round. The Super 2 is also in the stadium EQ wise.
My industry source says the Duncan has some fresh new blackouts models coming soon, tho, so I might have to experiment lol
