The Wizards can get great compression boosted, but still no sag. Still feel good to play and super rewarding when your playing is on point. Another one I'd recommend is a GZ MOAB+ on an old JMP or JCM800. All the open, raw, uncompressed goodness Wizards have in spades if you want it, but then goes from there to any level of compression and gain you'd ever want and everything in between. Little more forgiving low end response, still not a lot of sag but maybe more than Wizards depending on settings. Also, every bit as articulate/defined, and wicked punch/girth right there next to any Wizard.
