I have a Cold Sweat set in my SG Standard. Both pickups work well in an SG. Not sure how it would match up with an A-Pig, but I am assuming it will be fine.
I get a professional to make my harnesses, so it's not that hard! Should costs me around $130 including everything, Switchcraft selector switch and jack, CTS pots, nice caps, etc. Without the push-push pots it would probably be $20 less
