I agree with the Shiva being a great contender. However I sold my trusty Shiva after 2 years because I wanted an amp that can do 80s hardrock and Metallica kind of stuff, too. (don't want to sound like Metallica, but be able to play that kinda stuff without bass flub).
A few many amps later I arrived at what I wanted. A deep and thick, blooming lead tone like the Shiva but with a great transparency and tightness on low notes, also with good bottom end: The Cornford Mk50. If you get the MkII you got a great clean channel as well.
It's quite rare and unfortunately in the US very expensive, too.
So maybe if I was over there, I'd get an SLO.
