I just replaced a holy diver with a black dog a couple days ago
the black dog is a lot warmer and less in-your-face sounding
the holy diver was definitely tighter, more aggressive, crunchier, middier, louder and had more high end
the black dog is covered, though, the diver has open coils
boosted, they can sound similar with a small adjust (I use an equalizer), but without the boost they sound very different
if the diver sounded like Cantrell, like I always mention, the dog sounds like Thayil
wasn't impressed at first, but it's growing on me every time I play it
let's see if it will handle the band as well as the others did (this guitar had half a dozen higher output sets)
