i'm looking at getting a new bridge pickup for my old GRX that i've modded the hell out of. i've been looking at d-activators but the dimarzio site tells me little about the difference between the two and just about all the demos on youtube sound like they were recorded through a lead tank. anyone out there have experience with both?
I have a D Activatior I never used, couldn't tell you about the sound but I have no use for it now, would let it go for $22 (shipping included) if you're interested.
I have the D-Activators and D-Activator 7s, and I can say they're the most responsive pups I've ever played on. The sound cuts through great with them, and they have great output.

$22 for a pair is practically giving them away.
