Oh wow, yeah, I hadn't considered Q-tuners, and I'd never realised that normal pickups could slot in quite easily. Thanks man :) Lots to think about!
Blackouts have been more or less at the top of my list, since I have a set that I quite like in my Viper. I was just worried that the low B (or whatever it ends up being - I haven't chosen tuning) might mud out since the BOs are quite bass heavy, but I guess I can throw some heavy strings on my Viper to put that theory to a rough test.
I've pretty-much settled on a C-pig set for the Angelus, though :D And maybe a MM bridge to go with a P-rails neck in my SG. Ahh... pickups are fun to choose ;)
