I think some guys are WAY overthinking this, and letting speculative fine details get in the way of the important stuff.
I'm not saying this is perfect VH tone replica material, but it took maybe 10 mins total. I didn't reference the original, little care was taken - and still it's close enough for rock n' roll. More time messing about, post-EQ, dialling in the reverb etc would get it closer but whatever, it's just not important.
IMO here are the 'secret' ingredients to getting 90% of the way there (that we've all known since the 80's) -
1. A nice NMV Marshall type amp cranked up. This is our 69 Super Lead, but any quality clone can get you there.
2. G12M in a decent 412 miked with an SM57. This is a blackback, but earlier (or later) greenbacks work just fine.
3. A humbucker equipped guitar in Eb. Super strat, Gibson, whatever.
4. An appropriate riff played by someone with decent technique (I just qualify).
5. Don't be shy with the plate reverb.
Using 6CA7's, a variac, the right magic plckup, a JBL etc. may get you closer, but practicing an extra 10mins a day would probably make more difference in the long run.
In fact I think that a great player using this exact tone in a kickin' VH cover band would absolutely crush it. Happy to hear counter-arguments, but if someone could explain why this 'mystery' still needs solving I'll be impressed.
