Cool. Thanks. I don't have a Badcat, but I do have an "AC30-inspired" EL84 combo... Genz Benz Black Pearl, which has a Red Fang in it (alnico Blue copy). Just curious what Badcat was doing when they couldn't mix & match speakers.
Vintage 30 is nice, but so is a G12-65 re-issue. It's a bit more balanced overall without the pronounced midrange hump, but that v30 midrange hump can be just the right sound sometimes. I'm using two G12-65s in a Boogie 2x12 slant front cab with my Hot Cat.
