Hey Kristian! Long time no talk.
Just wondering how your D-Sonic is or was installed. I have one on the way, might be here in a few weeks. People say it's brighter, tighter and better for low tunings with the solid bar towards the bridge, and more solo-oriented and similar to a Tone Zone with the polepieces towards the bridge.
The Breed in the bridge is a very crunchy pickup and sounds great with Mesa amps, but it has a vintage vibe and too much mids; that's why it has to go. It lacks a little edge. Not sure about the neck model though, because it sounds a bit different when installed with the black cable closer to the neck. Might replace it with an Air Norton, or not.
Have you tried the new DiMarzio D-Activator? Not my kind of pickup, but would fit your needs very well, being a Super 2, Super 3 and EMG user for a long time now.
I had a Duncan Distortion in the bridge of an old Fender. Probably one of the best pickups for powerchords ever.
Keep heavy!
