Wow! That sounded... fantastic! It sounds better than the Ozzy version as you can hear your singer can actually sing and the guitars are more upfront. This is obviously no weekend thrown together tribute band. I assume the pickups heard are Miracle Man? Is the Talkbox part triggered via keyboard?
Do you use different BKP's for different phases of Ozzy's career Tim? For example say, Mules for Randy rhoads, Warpigs for Tony Iommi, Miracle man for Zakk, heh, maybe VHII for Jake E. Lee?
