Out of those the following would be my top three:
1. Rebel Yell
2. VHII
3. C-Pig
RY out in front by a margin.
A lot of the ceramic pickups sound very similar to me in this test. I would probably put the C-bomb at #4, but the C-Pig was more distinctive. I think that these riffs maybe didn't showcase the best aspects of some of these pickups, such as the Black Dog, and was more suited to comparing the ceramic pickups, but then again it made them all sound a bit 'samey'
