I picked up a older four hole Black Cat head on Sunday. It's been a few years since I've owned a Matchless HC-30. Without the Matchless to A/B, I think I find the tone of the Black Cat a bit better. It's smoother and has bigger over all sound than I remember the HC-30 having. I think I'm one of the rare people who like the Black Cat more than the HC-30. Speaking of big, the cab is huge. It's about the size of a Superchief, which is massive. It's not even a reverb model.
