A question of power

[Pale Rider]

Tough decision, indeed. I have the HD and its distortion character (or texture) is like the one of a JB but with more tone if that makes sense. Clearer and richer with fuller mids and low mids.

By VERY carefully listening to the clips of the site, youtube or any mp3s I found I can say that the tone I like the most is that of the Miracle Man followed by the C-Nailbomb. For Alnico pickups I'd go with the Nailbomb for sure even if the Diver is a very toneful pickup too. The Nailbomb has a classic voicing which is very close to the classic rock tones of the 70s we know.

If I was in your place I'd go with the Nailbomb just by the tone texture. I like it the most out of the 3.

the Nailbomb is actually more of a mid 90's tone
I always think of Helmet and early Silverchair
Tim usually recommends it for Tool as well, but I like the Holy Diver better for that (at least for their recent stuff)
the thing about the Nailbomb is that it retains that PAF hollowness in the mids, kinda like the Riff Raff, but thicker, more compressed and not as bright (the Riff Raff is a quite "twangy" pickup)
it doesn't have the "air" of the Riff Raff on distorted chords, though
it's definitely more dense sounding, despite of the "hollowness" in the upper mids
the Nailbomb is completely different from the Diver's texture and voicing, although they have similar specs and look almost the same on the new EQ chart
it's much louder, edgier and less middy
didn't try the nailbomb and warpig in the same guitar, but I had the impression that the nailbomb was higher output

Yeah that hollowness is what I'm talking about. It's cool if you ask me. I think Miracle Man has it too but in a more metallic manner and in low mids instead, making it sound deep and heavy.

I agree about the density of the Nailbomb too and the focus in mid-mids and upper-mids.
