I would look towards an Engl Powerball or a Bogner Uberschall.
WAY more musical then any Peavy or Krank IMO.
Both are tight and have enough gain to bore a hole in concrete!!
I've never been a fan of tube pres for this application...To soft. Prefer something tighter.
I'd look toward the usual guitar suspects....Neve, Api, Chandler TG, Pacifica,
etc. etc.
