The new Mesa Subway gear will kill for what you want and have the reliability needed on the road. Unfortunately, even used it’s not going to fit in your budget. You can still get a lot lighter than what you’re looking at currrntly if you can find used in good shape. It’s not really a vintage head, but I’d look for a used GK700RB and two 15” cabs if you can find them. Basically, I’d lean more towards reliability than tone for touring. Slay the tone in studio, get something that will sound decent but always work on the road.
