I think about pickups in a linear fashion. For example:
P90>PAF>Pat.#>Transition pickups>T-Tops>Circuit board buckers>490 series>Dirty Fingers
Then you have the Gibson Branches Branching \...........................\_>Shaws>57 Classics>Burst Buckers
Then you have the aftermarket progression..... \_>Dimarzio Super Distortion>JB>Duncan Distortion
I think the Super D is a REALLY cool pickup. It's ceramic and overwound, but it doesn't seem as far removed from a PAF, somehow, as a Duncan Distortion or even a JB in some ways. A JB is a more "perfect" sound than a Super D I believe. Some people think the SD is too middy, too dark, too fat. I think it does killer in a guitar you want to warm up.
