I have an SG with an Iommi in the bridge. I love it because it's big and really warm.
Right now in the neck I have a modded 490 with an A5 magnet. It's good by itself but really lacks some thing compared to the Iommi. Has anyone paired a Phat Cat with the Iommi or used other pups?
My other idea is to pop a BB with either an A8 in the neck to check it out. It would certainly be bigger sounding.
