Also, I own an Edwards Les Paul with Seymour Duncan P-90s and a Country Club with stock dynas, and I like the sound of the Club better. Two very different guitars though.
To me, the P-90s in the LP sound, again, thicker (but with plenty of nice detail because they are single-coil and hence are without the flatness and muddiness of humbuckers).
The dynas to me sound more distinctive, very three-dimensional with a slight hint of a nasal quality that's not thin but edgy and aggressive.
I'm not much better at describing these differences than I would be at describing wines. Also I've had my perceptions shaped by what people say. And I haven't fiddled with the tone knobs to try to make the two pickups sound similar, and haven't recorded with them much. But I do hear two distinct tones with these pickups.
